I see a few members have showed up 
I would definitely tell myself not to get caught up in all the petty side issues and ego trips of being a guitar player .
In the near future , good guitar players are gonna sprout like an invasion of sex crazed bunny rabbits and over populate the music business .
Even keyboard players that can easily outplay the best of guitar players are gonna start using samples of well recorded guitars and get into the act .Get used to that Idea , learn from them all , and use it to your advantage .
Be open to learning something new and useful in music . Hopefully something new in music that will translate into a musical skill that you can enjoy doing , get good at and use to be of service to your fellow man & woman in music .

The funny thing in my case is that I would probably recommend myself not to put the guitar away as much as I did between 2001 and 2010, and to challenge myself to at least learn new things, even if that wasn't going to end up on tape.
Coming from a rock and metal background, the new millennium was a challenging place if you wanted to maintain artistic integrity. Ever since grunge, playing with any sort of virtuosity has been frowned upon in popular rock music. I feel that it goes on to this day - it's all about texture, and melodies are kept to a minimum.
Unless you go full out "classic rock". But there's a cheesy aspect to that too. You can't exhibit serious rock star chops unless you mean it as a joke.
The irony being that there is an endless supply of amazingly skilled kids out there, but all they seem to do is to show off in front of their web cam and upload it on the web. Okay, most of them exhibit an absolute lack of emotion, but, hey...
Me I felt I had reached a plateau. I wasn't hot enough to shred like the hairy dudes. OTOH, I couldn't pretend to be Kurt Cobain either. And everyone had been abusing the SRV/Hendrix thing for over a decade, which had also been my thing...
Anyway - using those new tools that are accessible to everyone today, I can honestly say that my playing has improved dramatically, even just in the last few months, whereas, I was stuck in the same place for over a decade. I could and should have challenged myself before...
