The reaction of the world (friends, lovers, etc.) will interact with re-invention of the persona. It may not always be good. If you change one significant thing, you change everything. Be careful what you wish for. The world will be a mirror that you observe yourself in. You may not like what you see.
Also, once you change the world will treat you like a different person…which is what you want…you think. This may be expressed in unexpected ways which you cannot control. To this extent, you are as much shaped by the world as by yourself. Good thing though…you become more aware of the dynamics of the process and are not so much at its mercy.
