Why do I overestimate myself all the time?

I always do this. I work myself incredibly hard, I put loads of pressure on myself, I push myself to do, to think, to care so much. Then when something important is happening, I crash completely physically and emotionally, and I can barely live.

But, I guess forcing myself to care and to try new things constantly and live without restraint is better than doing nothing. It is so easy to be complacent. To live life in a stagnant way. And so many people in America (I don't know about the rest of the world) do that. They don't think. They don't challenge themselves. They don't even live, when life has so much to offer.

Even if it makes me tired beyond belief, I want to continue living my life! I want to live outside of myself. and enjoy what is happening right now, not what is going to happen. Of course I won't stop dreaming. I wouldn't be able to stop dreaming if I tried. I am just going to focus on Now.

Life. Now.
