This is one of many things and a superficial one (I'm keeping a few special ones private), but I'd like to be able to actually enjoy exercising. I'm exercising but I don't yet enjoy it (though I've been doing is religiously for 6 months now). I'm working on going beyond tolerating it and making it a habit to looking forward to it and enjoying it.
I also wish I could live more in the here and now rather than thinking about tomorrow/future. I'm working on that too. Unfortunately, one of my strengths is that I'm a good planner for the future, but that can have its downsides, too.
