unlearn shame. all forms of shame: unemployment, illness, vulnerability, longing, desire, errors, failures. you do not need to feel ashamed of what you are experiencing or living. freedom and shame cannot coexist.
Apply for as many jobs as you can. Target roles that are above your qualification. Go to the interviews that scare you. You will gain so much confidence from that experiece that you'll naturally become a better candidate. This is one of the things that job hunting taught me.
