Thank you dstrenz for your good tip. Walking is a very good excercise form and it is probably also a good way to get those creative juices flowing. Listening to music is also said to be helpful though it is something I don't do enough.

Creativity...we all have it. Some seem to have more than others. But I don't really subscribe to the belief that what you have is all you can ever have. I believe it is possible to nurture and train your brain to be more creative simply by working and practicing the things you want it to accomplish for you. 
 
You asked how we could Maximize it.  Rain pointed out, and I seconded, WORK, WORK, WORK.
 
Because the more you work on something and practice it, the more it becomes a part of you. You will find that as you work and practice, the creativity is more easily expressed. Your body and brain must have the proper tools in order to produce creative results that you are able to put into some sort of tangible form. Having brilliant ideas floating around in your head as fleeting thoughts does absolutely no good unless you are able to express them to the world in one way or another. Working and practicing gives your brain the tools it needs.
 
Some of the greatest inventions in history were invented by the unschooled.  For us in the world of music, some of the most amazing music/songs, have been written by the so called uneducated, unschooled, of the musical world. It was said that Lennon/McCartney couldn't read music. IDK if that's true but they were certainly not musically educated in the classical sense of the word with college issued musical degrees. They were ROAD scholars having a vast knowledge of the things they wrote about based on real life and banging on a guitar with 3 chords and playing in dark, smokey nightclubs.
 
Would a degree in music be an asset? Possibly so, possibly no.   Education in and of itself is of little value vs being able to create and express that in a way that the people listening can appreciate and relate with. 
 
I have known many highly educated musicians...our church's music minister was one of these folks.... a totally amazing piano player...... masters degrees and more, could play multiple instruments, and can read and play anything you set before him on sight. Yet, ask this same person to jam in A with a 1,4,5 progression and you get blank stares. These same folks express sheer amazement that someone without any education could write a song.  Yeah, he even asked me "how did I do that?" after hearing some of my songs.  They can easily get locked into a way of thinking that inhibits the creative spirit by all of the rules and things they have learned on how "it's supposed to be done. 
 
So YES.... by doing the right things, over and over.... practicing and working hard the RIGHT way, you can in fact, maximize your brain's ability to be creative.  No musical degree needed..... just the willingness to invest the time in doing the right things.  As a songwriter, that means writing, writing, writing, and then writing some more. Ignore the clock and the calendar..... write, and as time passes, you will notice that writing becomes easier, the results tend to get better, and you will see improvement over time.  Steel sharpens steel, so as part of that work ethic, work with others who have the same passion. The things you will learn from others will be amazing.
 
my 2 cents more

Thank you Guitarhacker for ideas. I gotta continue working then. Maybe some day I can be satisfied with what I can do.

Although creativity cannot be manufactured,  I do think it is spurred by practice and trying things that keep us from making practice too robotic. Some of us have trouble coming up with routines that ignite that spark that enforces habits that lead to creative thought. I have found that sometimes formal training impedes my creativity. I emphasis sometimes because I occasionally forget to toss out what i think i know and it gets me in a rut.

Thank you dubdisciple for your tips.

I don't know whether it's the fact that I did receive formal training for it, but for a while it certainly became very hard for me to create on the guitar, as I was just too self-conscious.
 
I hated the idea of showing off just as much as I hated the idea of writing unchallenging things, so I was stuck in the middle. That's when I became my own session musician and only though of guitar parts from a producer's perspective. And I know others experienced similar phases.
 
I've managed to restore that balance, but it remains that I'm always more inspired when playing an instrument I'm less familiar with. It's just easier to forget about yourself and see the big picture - instead of agonizing over the fact that this chord pattern has been used before. It helps restore that naivety which I often find quintessential to creativity. There's no "you can't play that!".

Rain, I think we areb in agreement. I think in all art forms, having that deeply ingrained base from years of practice frees you to create rather than get frustrated by misplayed chords etc. Frustration is a creativity killer and I know nothing kills my mood quicker than when my lack of practice makes simple things harder than they should be. Balance, as you mentioned works wonders.

Absolutely.
 
Incidentally, not that long I was preparing the studio for a session with my wife and I realized that I tended to ignore a lot of things which I do for others when recording myself.
 
Dimming the lights, making them feel comfortable, turning on the lava lamp, giving them room to move around a bit, creating a mood - these are all little things which can make the whole recording experience run smoother than if you're just trying to execute your part in between two other things.
 
This was one of the points in re-painting the room a creating an environment I felt inspired by in which I could move around a bit, instead of piling gear everywhere. I also try and plan actual recording sessions - allocate a few hours just to play and record guitars, instead of simply recording tracks in a rush between programming drums and comping vocals. 

Just do what you want to do, not what you think others want to hear. Magic moments happen so infrequently, you have to create frequently to find them.

Thanks guys for the good advice and tips. I may be stretching my luck a bit but if you have the time and feel like it maybe you could participate in my forum improvement thread here:
