Achieve financial freedom before age 30 by doing these ten things right:

1. Extreme Saving: Save 50%-70% of your income, prioritize saving before spending, and allocate part of your salary to savings after raises.
2. 4% Rule: Financial independence funds = annual expenses x 25, relying on a 4% annual return to cover expenses.
3. Compound Interest Early: The sooner you start investing, the greater the difference time makes.
4. Passive Income: Build passive income streams such as dividends, rental income, and royalties.
5. Minimalist Lifestyle: Reduce material desires and strictly control unnecessary expenses.
