I have some basic pieces of financial advice in addition to budgeting:
1. Your 401k contribution needs to be at minimum to the point the company match maxes out.
2. Whether you dump monthly savings into eliminating debt or into other retirement investing, if you do either consistently and aggressively you'll be in great shape.
3. If you invest on your own it is tough to nearly impossible to beat Vanguard index funds
4. Early retirement is MUCH closer to reality than most people think. The best way for most people to get there is through minimizing costs in an aggressive, yet sustainable way.
5. Most people, especially financial planners DRASTICALLY overestimate the amount needed for retirement. The Trinity study on stock ROI basically concludes that 4% after inflation is a very conservative expected return. In other words, if you save 25x your annual expenses, you could actually probably retire. Also, most people simply spend way more money than they need to get by.
6. Don't get caught up in comparing your house, trips, cars, etc. to other people. Most people are overleveraged and are very stressed about money.
7. Don't buy a depreciating asset on credit.
8. Learn to do hands-on things like home repair, car maintenance, etc. on your own. Not only does it save you a ton of $, you'll feel good about learning new skills.
Hats off to the youngsters on here starting jobs and already thinking about finances in such a serious way. I wish I had been smart enough to take it that seriously when I was in my early 20s.
