It’s not about making the right decisions, it’s about making the decisions right.
Whenever we decide on a goal to pursue, we are not in full possession of the facts when we make that decision: none of us can predict what will happen in the future. We will only know if it was the right decision after the event.
So lets forget about worrying whether we’re making the right decisions or not (in fact, that way lies procrastination), let’s simply decide on the goals we want to accomplish, commit fully to them and be determined to find a way of getting them done no matter what.
Make the decisions right.
