Analyze your problem more deeply. The real problem isn't that you hit something too hard. It's one of the following:
1. Somebody is mad at you for hitting someone or something too hard,
Solution: Hit the person mad at you harder.
2. You broke someone or something too hard, broke it, and now you need it.
Solution: Hit the other people around harder until they agree to bring you a replacement.
3. You hit something too hard, and now it's stuck.
Solution: Hit it harder from the other side.
