Above all, avoid lying, especially lying to yourself.....

“ Above all, avoid lying, especially lying to yourself. Keep watching out for your lies, watch for them every hour, every minute. Also avoid disgust, both for others and yourself: whatever strikes you as disgusting within yourself is cleansed by the mere fact that you notice it.Avoid fear, too, although fear is really only a consequence of lies. Never be afraid of your petty selfishness when you try to achieve love and don’t be too alarmed if you act badly on occasion. ”

Fyodor Dostoyevsky
