I have a post coming down the line about turning 30, which I did last week, and all the things I am planning on figuring out this year to be a grown up for real. But while formulating my plans, I stumbled on this gem [link], which could come right out of my subconscious. I'm the queen of talking myself out of things, not always for the reasons listed below, but for reasons as mundane and dream-crushing. Funny how we have a tendency to give ourselves outs for our dreams and goals. If we can talk ourselves out of starting, there's no failing, right? No looking stupid or regretting things done.
"Don't be silly" "Focus on X, not Y" "You're too young. Too old. Too unfocused. Too dignified." Why bother starting a new career or hobby? What bother bettering yourself, you were born that way.
Defeating self-talk is what it is. Pick your poison!
