Haha, your post hit me right in the feels! You're not alone in the "squandered talent" club. I'd say I'm a master of the "jack of all trades, master of none" approach. I can write decently, play a few instruments http://www.fusionmagazine.co.uk and even code a mean website - but I never fully commit to anything. It's like I get bored just before I reach the point of "good."

I feel your pain on the drawing side too. I used to love it as a kid, but somewhere along the line, the pressure of perfectionism took over. Now, the blank canvas just stares back at me accusingly. Maybe we should start a "Procrastinators Anonymous for Untapped Potential" group?
