Getting confused and not starting is worse than failing after dedicatedly going down one path.
I always try to think of a Plan B, and trying to cushion a fall that may never occur in the first place. This "cushioning" effort takes away time and effort that could go into executing the original plan with full gusto.
Uncertainty is constant. Hence, I want to dispense with Plan Bs, trust my instinct and skills and go for the kill with full gusto. Now, I need to find a worthwhile target, that's all. And concentrate on it.
