My plan is similar to yours, but isn't limited to IM. It involves me getting better at all the things/hobbies I've taken up in 2014.
1- multiply earnings
2- improve guitar playing skills
3- attain better physique
4- read more books
5- expand social circle (as you all know, connections are a vital part in business)
6- fill in as many gaps as possible
7- think of new ways to make money, maybe?
I don't think I'm going to take up something new this year though, as I'll be focusing on improving what I have. But that doesn't mean I won't learn new things, or develop new methods or ways of thinking, be it in IM or any other part of my life. That's about all I can think of right now, so it's going to be one hell of a year. I'm still young compared to most of you here though, so I believe 2015 is going to be a kind of base/preparation for what I plan to do for the rest of my life.
