I just recently graduated college and have begun my life working in the "real world". As a result, I want to make sure I am doing everything possible with my money to improve my life/future/retirement/etc. going forward. I would greatly appreciate any personal finance advice regarding investing/IRA/401K/budgeting/credit building/etc. for me to do now (age 22) in order to be thankful later. For those past their 20's, is there anything major you regretted not starting earlier?
I feel this thread could be a great resource for all students/young professionals.
