>>13093136Mine came half from a delusion I had about a girl I worked with being in love with me, which instilled in me such great (minor) confidence, and then the other half from her crushing my delusion and dealing with the fallout. I went through periods of complete blinding optimism and self-content, and then bouts of depression, until stabilizing a bit when I decided to quit my habit of thinking entirely (in a way). I still have those bouts and periods at times, usually in times of great anxiety and terror, or when I'm drinking.
So you can try that :)
But more in your reach is literally just loving yourself and thinking you're the greatest man on earth, ironically. It's really really funny and entertaining at first if you have no self-confidence, cause you know it's so obviously bullshit, but over time you actually start to believe it. It's a good feeling.
But godspeed.
