What do you wish you had done differently in your early 20s?

Please bare with me, I’m entirely new to this space but I find it all inherently interesting.

So for context; I’m 21, I was in foster care and I have just graduated university with a law degree. I have already got a job as a paralegal and i am projecting to qualify as a solicitor (UK Lawyer) around my mid to late 20s.

I’ve always flattered the idea that law would be just my stepping stone into property investment, but never truly considered it all. I want to hit the ground running, and come to realise the way I play the game right now can make or break my future FIRE status.

Maybe I’m not as optimistic as some on this Reddit. I’m not looking to make £5m or anything. But I I would say having a healthy £300k by 35> is the goal right now.

So, does anyone have any tips or advice that they would bestow on an early 20s version of themselves. What do YOU wish you knew?
