We tend to overestimate what we can do in a short period, and underestimate what we can do over a long period.

I grasped two things: I wasn't as happy as I could be, and my life wasnt going to change unless I made it change.

Often, if there's something that I want to do, but somehow can't get myself to do, it's because I don't have clarity. This lack of clarity often arises from a feeling of ambivalence - I want to do something, but I don't want to do it; or I want one thing, but I also want something else that conflicts with it.

One reason that challenge brings happiness is that it allows you to expand your self - definition. You become larger. Suddenly you can do yoga or make homemade beer or speak a decent amount of Spanish. Research shows that the more elements make up your identity, the less threatening it is when any one element is threatened.

If you want to feel safe, healthy, and hopeful, try to act as if you did feel that way. "Fake it 'till you feel it." maybe start with health -- try to walk energetically, speak energetically, do physical things.
