Have no mentors…need some life advice

Hey grapeviners!

I am 23, live in Bangalore, earn around 67k per month and pay around 13k for rent.

But on average monthly expenses come to around 40-50 with everything including tickets and all.

Also, I feel I have more earning potential but I am also scared of switching jobs as of now.

I am in a marketing/content role and I understand branding and stuff but feel I am not good enough, though I have always been loved by my clients and managers.

Need some suggestions on how to take the next big step. How to earn big money.

Ps: no privilege background.
