if you were 22 again, what steps would you take to thrive in your 30s?

22F here turning 23 soon. i’m a firm believer that 30s is the new 20s, and my biggest goal is to be content with where i am by then. i’m a student graduating college in a couple weeks and am in the process of finding a job. up until now i’ve kind of just been ‘existing’, meaning staying in my comfort zone and not pushing for potential. i don’t want to make the same mistake and regret not taking action. my biggest struggle is making use of my time and being productive. i am open to any kind of advice, from things you would have done differently in your 20s, to habits that made you grow as a person.
