Please Use A Deodorant
This can't be overemphasized because I'm tired at having my stomach churn at the smell of people. No matter how bad you smell from sweat or whatever, a nice fragrance would help mask it at least. Think of others and the environment before stepping out of your homes.
Be Nice
The world is hard enough, don't make it worse by mistreating others. It's only reasonable to treat everyone like the human that they are.
