The Bottom Line
Putting together a forecast isn't difficult if you just use your goals as a guide.

In Detail
Thinking ahead can be daunting. There's no such thing as a crystal ball, and sometimes when you plan too narrowly, you end up making dangerous assumptions. To avoid the pitfalls of forecasting your life, don't get too tied up in timeframes. Just think about what you want in your life and go about getting it. Recent bad habits are preventing you from expecting the best of yourself, so add more discipline to your life and say 'no' more often. Perfection isn't the goal -- happiness is.
