What does respect yourself first mean?

It means that if you hold yourself in high esteem, others will do the same. Carry yourself with respect and other people will respect you. Teach through actions and treat others like you want to be...

Yes..

Yourself is made up of two words, your self. It basically means you. Its not a hard word to understand.
