So i recently started a job after being worn down by uni for years - completely messed with my perception of my own skills despite scoring among the top grades that year.

I figured the job was a fresh start, and that I'd go into it by just faking confidence and comfortability with my role from the start. Internally i was constantly belittling myself, but people only noticed a confident person not being afraid of taking on new tasks - and it WORKED. Coworkers keep praising me for stepping up and trying. 2 months later my mindset is changing to focus on maximizing successes instead of minimizing mistakes. Any mistake is just a learning opportunity to perform better next time.

It's super cheesy, but faking it can change your mindset really fast.
