This way or that?

Making a decision is sometimes an exercise in self observation. It throws light on the double edged nature of the mind.
This is most apparent when the choices on offer are of equal measure but divergent in nature: career decisions, choice of a life partner, and, changing professions in midlife are examples of such junctions of life.
What appears as solid and most apt looks like an illusion and completely unworthy after a few hours. A few words of well meaning advice from friends and family can turn the tide and yet again you are back to thinking, "what if I chose the first option, rather than this one?" after a while. It can be tiring. You feel as if your own mind cannot be trusted for suggesting to you the right direction of action. You are left in the lurch by your own mind!

All options are good to start with, and yet in practice, you can go along only one path. What to do, becomes a harrowing issue.
One small way out is to imagine how it would feel some ten years down the line if one chooses one option versus another. The emotion attached to that option would perhaps be a more accurate guide. If the option works out well, good, if it doesn't, at least your heart is not pained about the decision.
Have you come across a better way of dealing with such issues?
