I think the basic issues for me are around
- Getting out of the comfort zone. The existing mental pathways are easier to go along with.
- Trying to look for "productive output".
- A belief that any new field requires a huge amount of practice and dedication.
Due to this I always ended up spending my free time on the next "scripting language" or "programming model" :). So taking a different view point and approach, I am going to:
- Focus on the joy of learning/exploring something new.
- Commit a fixed time (say 30hours) to a given field and see where it goes.
At the end of it if I can enjoy/appreciate music or photography more, it would be more than worth it. RK's tip is a very practical fallback :)
