Decision Making

Have you ever doubt your decisions? If so, what do you do? Bite the bullet and stick to it? Seek advice and rectify it?

Why will people doubt their decisions? Is it because time changes, and people change too? Thus, what seemed the best and most logical decision may become illogical and bad? If so, whose fault should it be? Yourself or the environment?

If your decision involves other parties, what will you do then? Keep quiet? Talk to them? If people around you regret their decisions made, what will you do? What will you advise?

Are there really wrong decisions made? Or is change the only constant, thus, the different perspectives at different times?
