Love yourself 

Never try to prove yourself in front of other's... if they know you then they understand you or if they don't then never live in illusion..

Never try to become like other's if they love you they accept you as you are..if they don't then obviously they want change ..

Never feel sad for your bad situation ..if you won that situation then you become successful

Never trust anybody whose only intention is to make your relationship worst ..if they done it then you loose it.
