a thought: history of self and destined failure

do you people find that it is in your intelligence and/or physical ability to accomplish certain things, but your confidence or lack thereof prevents you from doing so?
what if you were given a chance to forget your notions of self? do you think you can start afresh? or are you destined to repeat failure.
seeing that at times,our ego is as it is because of who we are, it may be futile to ‘forget our notions of self’.

My unconscious mechanisms own me. Even though I am conscious of their failures they still have power over me.
