I really do what to be able to run, but now is not the time. It's something that I want, but it's not something that I love (yet).
So, I'm going to focus on my other fitness activities - weight lifting and MMA training plus cardio, either walking or on the cross-trainer.
This decision of mine is actually not just about fitness. It's about me finally realizing that I can't do everything, and that it's ok. There have been way too many times in my life that I have done things I didn't want to do or that I've sacrificed things that I really wanted to do for things that I interpreted as things I 'should' do.
Instead of overwhelming myself, I'm finally making decisions (that are becoming much easier to make) in favor of the bigger picture -- in favor of making myself happy in the long term, not just right now.
