Cheers for the responses guys! Looking back through my list of unfinished bits and pieces. There was one file in particular that made me both laugh and feel sad, all at the same time. It was truly a monument to misspent hours of dicking around, instead of playing.
 
The first four tracks in the song were about 42 seconds of an intro and verse, that consisted of drums, electric bass, synth bass and a rhythm guitar. However, there was actually forty something instruments and synth sounds loaded for the project in total. With a pile of midi tracks containing the same copied and looped midi progression, of C-D-F-G.
 
These notes had nothing to do with the song. I'm guessing I just entered some data so that I could hear the instruments being triggered by something? And here is the kicker! Some of the outputs even had effects automation, dynamics processing and bus sends. Yes that's right. I started mixing test portions that were never going to be in the song. Hence, tweaking dials leads me to more tweaking of dials.
 
With all the other instruments muted, the first four tracks were actually really catchy. I can't believe I let my train of inspiration get so derailed?!! So last week, I sat down to work on this song. I stuck to my plan of limiting options, by picking the best 10 or 12 sounds that I'd created and deleting the rest. A little over two hours later and I had 4 minutes and 39 seconds of intro-verse-chorus-bridge-proggychangeup-verse-chorus-outro. 
 
There are still editing and mixing things to be done but most importantly, all the song parts are there. An almost 2 year old tidbit of nothing much, is now A COMPLETED SONG!
 
I'm not really religious in any way, but can I get a hallelujah?!!

Good thread! Should be a sticky (stickie?)!
 
I find my self deleting loads of .dlls every year, just getting rid of stuff I don't need, use or want. I'm getting a lot more done now!
 
Now I'm thinking of ditching my desktop DAW all together and move back to using only a laptop and more limited machine power and fewer samplelibraries. My first computer was a laptop, that's what makes me feel comfortable and connected to what I'm doing. I bought a new laptop this summer and I feel like a kid again when I boot up some music apps on that.
 
Simplicity spark creativity, at least with me! Sometimes it's good to take a dozen step back and see that your head is stuck up your rear, pull it out and move on 

I started years ago collecting tons of vst's that were free. As time went on, I realized that I tended to only use certain ones.
 
So when I built my custom DAW, and it was time to reload the software, I only loaded the stuff I had used in the past 60 days. Lots of things were not loaded.  Amazingly, I don't miss them one bit.
 
So now, I have a very small group of VSTs, synths, samples, and FX that I consider my GO-TO list. It certainly makes life easier in DAW-land. 
 
Just like the guy who has one bass guitar hanging on the wall, I use the same bass sound on every song when I'm playing the bass part on my midi keyboard. I like the sound and it works for me.
 
Keep it simple..... and less is more.
