Ask HN: What were/are you doing at age 25? What would you change?

For those of us without something to compare this stage of our life to, I was hoping to get some insight on how people handled/are handling their lives at around 25. At least for me, only being 2 years into my job I still feel like I'm thrown into a pit (a consequence of the job offer I took, I suppose, and complacency).

As for the second question, what advice would you give a 25 year old you?
