Growing wealth is simple. Most people make it complicated.

Build the boring portfolio. Retire on your terms.

Grow your skills. Trade them for a better salary. Save what you can without sacrificing your life. Max out tax-advantaged accounts (401k, ISA, pension). Dump the rest into low-cost, globally diversified index ETFs.

Don't know how to do all of that? Fire Tools does the math for you.
