Become wealthy within ten years

Avoid debt.
Nothing is worth paying interest to own.

Avoid financially-irresponsible people.
Never even dare to marry one, as they may hinder your growth and prevent you from achieving financial success.

Spend the next decade or so working your ass off building your career and your professional reputation.
This is not meant to suggest you must be some sort of office drone. The possibilities are endless. You could take those low-cost college living skills you’ve honed and use them to pursue any number of new adventures.

Live within your means.
Avoid expanding your lifestyle.

Save and invest at least 50% of your income.
Put this in VTSAX or other equivalent investments you’re knowledgeable about.

Fund any 401k plan offered to you and your IRA.
401(k) is a retirement account offered by your employer, while IRA is an individual retirement account for your personal investments. Both of these will be your major sources of income for retirement.
