If you do not set unrealistic goals and targets, they can almost always be achieved. No stress that way, but if your goal or target is not reached, and it was a reasonable goal, then you look at why, what caused the failure, was it internal or external or something you had no control over. Not reaching a goal or a target should not be a stressful thing, it should be a learning thing. I do not understand why people stress over not reaching a goal or target, if a person is stressing out over not reaching a goal perhaps it is because they can not look objectively anymore as to why they set the goal in the first place.

So I do not stress over missing a goal or a target, just how I am I guess.
