Usually the problem is that you think about doing things instead of just going ahead and doing them. When you spend your time thinking instead of doing, not only you waste time - you also find many problems and use them as excuses not to do the thing you want, or delay it. Most of those problems are pretty easy to solve by crossing the bridge when you reach it - which you won't unless you stop thinking and start doing. Now, I don't say you shouldn't plan - doing stuff without planning is not always wise - but you should limit your planning to the preparations, not to the actual acts. Remember - instead of thinking about what you want to do - just do it. If that advice sounds stupid and cliche - that's because you are thinking about it, instead of doing it!
