Instead of agonizing over which decision is right, randomly choose and make whatever you _picked_ right. Even when you're facing a major decision, it truly doesn't matter, because you won't have any point of comparison. Say you're choosing whether to have children. If you do have kids, you just _can't_ have any frame of reference for what life would be like if you hadn't. If you don't have children, you have no way to know whether having children would have been better or worse. So don't presume that the other choice would have been better! You have no way to know. Be satisfied with your choices; regret is mindless.
