Making difficult decisions became so much easier when I realized:
a) that the fact that the decision was difficult meant that either choice had a close likelihood of turning out well.
b) that the biggest mistakes I have made tended to lead to my biggest successes.
c) Sometimes, you perception has limited you to choosing between two choices. Change your perception enough to see that there are always a multitude of choices. You may not want to pick the 3rd+ choice, but knowing that you made your choices freely allows you to own the choice and the outcome.
The same thing from Joe Simpson in Touching the Void: "You gotta make decisions. You gotta keep making decisions, even if they’re wrong decisions. If you don’t make decisions, you’re stuffed".
Not choosing is a choice as well, the truth is that there are so many possible timelines but we will only ever experience one. So I would get comfortable with not knowing :)
