Eat twice daily. Have good breakfast; and for lunch you should eat something you really love. Skip dinner. People should not live just to eat, but eat to live.

Be kind

Hang out
Talk to people. Hang out. It will make you feel beautiful and accepted. It is essential for the man not to be alone and lonely because such a situation can leave lasting effects on mental and physical health.

Entertain the mind
