What if THIS happens? What if THAT happens? I spent a large amount of my life worrying about if, this and that. I think I must be one of those people who wasted their life thinking more and worrying. Okay. So enough about the problem, what about the solution. It's simple actually, you do things and then worry about what now. Sometimes taking the actions, even if it is wrong (within terms) then worrying is fine. You can easily get over the problems if you take calculated risks and think later.
