Dude. The fact that you're even putting in money is amazing! I'm sitting on 6% as well, due to a bunch of debt that I want to get more of a handle on before I even attempt to raise that number. Retirement planning is a wild horse that is different for every person. It also depends on where you might be living, what you're making right now, and all these other variables. The fact you're thinking about it and putting money away is way better than some people I know, who are in their 40/50s and don't have any money in their 401k.
