If i had a fight, what tips would you give me?

For example how to punch harder, how to prepare etc.

Don't punch at 100%, it will hurt u just as much as the other person... Try hitting them at 70-80% and protect your face

Hands up, straight punches, dont forget to breath

Work out and get stronger. Take karate or something to make yourself a better fighter. Not much else you can do.

Train. Or run.
