If you don't want to be you, become someone else.

"You" are only defined by your current state including your personality, appearance, and possessions.

The easiest thing to change first would be personality, so try being the change you want to see in the world.

Help others.

Try learning new skills towards being the person you want to be.

Then, comes appearance.

Don't like your hair? Try a haircut.

Don't like your clothes? Modify the clothes you have or buy some new ones (possibly from thrifting, if you don't have a ton of cash).

Finally, comes possessions.

Save up to get the things you want.

Or, if you don't want anything, sell it all.

Who you become is up to you and if you want to throw yourself away, then turn into another person.
