Some rules I love-
1. Buy a house that you want to live in and after that stop speculating on houses.
2. If you need to pick stocks, pick ones with trustable management and with low p/e ratios.
3. Also buy some gold as a hedge occasionally. (not more than 10 pct of your net worth)
4. Don't get obsessed about your savings. Invest in yourself, invest on your skill sets so that you can earn more later.
Good luck
