My simple way is taken from the book The richest man in babylon. 10/20/70

1. Protect you most important asset (that's you)

2. Save (in vehicles that earn uninterrupted compound interest)

3. Payoff debt (using the Cashflow index method and the roll over roll down strategy)

4. Invest (in things you know about and are interested in)

Another acronym I use is SAAW

Secure Accumulate Accelerate Wealth!
