Bad experiences are inevitable. You can’t avoid them. And yes, even people that seem as if they have everything figured out encounter them.
What makes the crucial difference though, is how each deals with such circumstances.
You can’t control what happens to you. Everything can be taken away from you, except for one thing. Your freedom to choose how you respond to certain events and how you deal with the feelings that those bring up.
Most of the time, acceptance is the ultimate way to turn a negative experience into a positive one. Especially, if you’re not in control to change your situation, practicing acceptance is a necessity.
Worrying has nothing of value. The only that result from breaking your head over things that are not yet there or can’t be changed anymore, is a loss of valuable time.
Accept and move on. Accept and act.
