To dwell on the past choices we have made and wonder at their results is a good way to bring yourself to indecision. The same goes for over-analyzing current choices and how they will affect the future. We live in a beautiful, chaotic world. If you have ever heard me talk about the concept of infinity and infinate results, then you will understand a little of what I mean by that. Accept the chaos for what it is. The chaos does not stop by analyzation and the chaos gets worse by over-analyzation. Make the choices that you feel are best for you in the now and let the future, the chaotic future , take the form it desires.
