You don't realize it yet, but you're too enmeshed with your parents. It's OK to live your life based on what YOU want, not what would please them. It's OK not to tell them everything. Start now because if you wait until you're in your 40s it's going to be even harder to try and separate yourself.
This really hit home for me...I am still very enmeshed at 32 and am now trying to tell myself to live my life based on what I want and my goals.
What I would tell myself (I have always been fairly frugal): College and First Job timeframe, 18-23 years old
1. Even though the scale does not say the number you want: you are thin and beautiful, strong and healthy. You will look back after kids and wish you could be that thin and strong again.
2. Live up to your own values; having a closet full of lilly pulizter dresses and jewelry from Tiffany's doesn't make anyone a better person or even worth looking up to.
3. Travel more (it is sooo much harder with kids)
4. Build better relationships with friends and then nurture those friendships
5. Don't listen to your father when he tells you not to put money in the 401k at your first job
6. Contribute to max 401k and Roth IRA...why do you need all of that money in your savings account not doing anything for you??
7. Invest the money you save monthly for "rent" while living at home
8. At work, know your worth and don't feel guilty about pushing for promotions, raises, etc.
9. Be more adventurous and enjoy life!
