Often we would make a decision to do X using a justification that time later proves was in fact of indiscernible value, meanwhile X turned out to be crucial to our progress.
In other words, whenever you have a feeling that X is a right thing to do (e.g. commit to a project, start collaboration, enroll into school etc), even if you don’t have a good justification at the moment, you probably should still pursue it, because right things lead to good progress in areas that you did not see beforehand.
Consider an analogy: it’s dark, and there is a street light; you can only estimate the progress within the area highlighted by that street light. If you thinking about doing X somewhere around the corner, in what seems to be dark, you can’t estimate really well what it’s going to entail. But you know that you are on a street, and there is likely another street light nearby. Go for it then! Take a leap of faith and hopefully some good things will shake out of this endeavor!
