1. Cleanse Thy Earthly Vessel

Start by getting your personal hygiene in check, have a bath, wear a scent, put on good clothes that makes you feel good, because this is the character you're playing, if you can't take care of yourself, you're less likely to get other aspects of your life in order. Being clean and feeling fresh all the time will increase your self-perception and boost your confidence over time. LET IT BE A RITUAL.
