I've given up on a lot things that I thought I'd really enjoy and this post gave me some great insight into how to overcome the feeling of 'must'.
A great example for me is my guitar playing. I have been at the same skill level for a very long time, for some reason practicing and progressing became less of a hobby for me started to feel like something I was forcing myself to do, so I quit trying. I now just fumble around with the same stuff that I have been doing for years. But the problem is, I really WANT to get better and really want to progress... it's just frustrating because it feels like it's without purpose.
However, I think that by doing what Jonanthan recommends, I might be able to overcome the obstacles that have set me back.
I'll be working through the "What would happen if I did?" and "What would happen if I didn't?" questions and I'll post the results here next week.
In the mean time, do you have anything that this might help you with?
