Stay motivated

A moment of motivation can change someone's life. A moment of despair can poison that one's life. So, fill your soul with motivation, then hope will always be by your side.

Put yourself first in his shoes

When you want to give someone a piece of advice, put yourself first in his shoes and take it for yourself and let your heart taste its bitterness or hurt and then throw away the idea. This person has much pain than you may imagine that a few words may stab him deep without you knowing.
