We can get caught up in the action, execution mindset and not see the joys of doubt, the moments for thought which we all need. If you’re not having any second thoughts at all, it’s probably because you’re not thinking it through enough.
The hallmark of the true believer is that there’s no room for judgment. For everyone else, misgivings are a sign that you’re carefully considering the problem at hand. Take your time and think it through, not too long but the time it and you deserve.
Doubts are good, confusion is excellent, you questioning life is the right thing, it shows you are engaged. Everything I have just described is showing you are seeking wisdom, you are actively expanding your mind.
