Now that I am not working I look at my shoes, my purses, my jewelry, and clothes that I HAD TO HAVE and think "where am i going to wear this stuff now?" Most of my days are spent in yoga pants and T-shirts. Thankfully we are not at a point in our lives where we would need to start selling all that stuff because we don't know where we will get money to pay for the mortgage.
Things I did learn along the way:
1. If you can afford a hight rent payment it's better to buy a place (you can change the wallpaper).
2. ALWAYS put aside 10% of your income for a rainy day. working at the same place for 10 years I was able to set aside enough to not have panic attacks.
3. Splurge every once in a while! We work our buts off and there is no point in doing all that to get to a point in our lives where we think "why didn't we..."
4. Cleaning your own home keeps you humble. It does not matter that you are wearing $30 Chanel nail polish when you are on your hands and knees cleaning toilet bowls.
