How to Completely Cripple your sense of self:
1) Don't do what social pressure says not to do (Even though you know it is right/what God wants you to do.)
2) Do what social pressure says to do (Even though you know it is wrong/what God does not want you to do.)
(These methods of crippling self are both true even when the social pressure is apparently telling you to do something that 'society' disapproves of, or not to do something that 'society' approves of. For that's the modern illusion - that by somehow rebelling against status quo you are actually achieving the opposite of crippling your sense of self by bowing to society's pressure, when those who are saying 'rebel with us' are quite simply creating their own mini-status-quo. Then you have the situation today, for when everyone is rebelling, no one is rebelling. )
& How To Strengthen your Sense of Self:
Give up your self to Jesus. Quite simply, let Him be King over your entire life. Let His word be your guide-book, let Him guide you Himself.
"For whoever wants to save their life will lose it, but whoever loses their life for me will find it." Matthew 16:25
