You were born with a natural sense of self esteem. The only thing that can change that is to allow negativity, whether from your own thoughts or from others, to damage you. Respect the sacredness of your being and only allow positive, affirming thoughts to enter your mind.
SECRETS Nobody can guard your secrets better than you, so do not blame anyone for revealing your secrets, because you could not hide them yourself. Your secret is your prisoner, which if let loose it will make you its prisoner. -Imam Ali (AS)
