Be decisive even if it means you’ll sometimes be wrong.
More time does not create better decision. In fact it usually decreases the quality of the decision. Decide fast, and trust yourself that you made a right decision.
The only exception – you need more information. More time without more information just creates anxiety, not insight.
Why should you decide fast about everything? Deciding fast saves time and frees a lot of space in your head. That space can be used for other more important thinking, for example creative thinking.
Rule your mind or it will rule you. – Horace
