My 401k at my current job reached $10,000 a few days ago. I feel like that's a significant milestone in my journey and I'm excited! I started contributing to that account August of 2010, so it took me 9 months to stock up 10k. Granted, my entire retirement savings is around $16k, but we all like nice round numbers. Also, I think it's a good gauge of what I'm capable of now that I have a plan because during those 9 months I wasn't really focusing on saving.
Ok, I'm done bragging now.
