Keeping it simple

My brain seems to love complexity. If I could think more simply about problems, I'd probably have fewer of them. For example, there's my tendency to procrastinate. I often put things off, not on purpose necessarily, but more than I should, which allows for problems to grow and become more difficult to solve. My brain seems to love these situations and performs relatively well in small every-day type crises. Give me a real crisis, though, something important or life-and-death, and I'm not sure I would handle it all that well. Still, my brain seems content to let certain problems build and build until they reach this low-level crisis mode and I'm constantly reacting to these situations that I should really have taken care of earlier. Another tendency I have is the tendency to blame myself for everything, whether within my control or not. If something goes wrong, I blame myself in a vicious cycle that prevents me from solving the real problems I face. I'm not saying I'm never to blame for problems, but the fact is I internalize criticism and beat myself up instead of keeping things simple and letting go of things I cannot control. So, I need help to simplify my life and thoughts, learn to rely on God more, and keep myself out of crisis mode. Any ideas out there?
