Before I was married I just had most of my money in a savings account. My wife started investing our money when I was 30 in mutual funds and maxing out our company matched IRAs. We consolidated all our different funds with Fidelity, and had them invest in more aggressive stocks.
Because we left the investments alone and continued to invest any excess money we had, I was able to retire this year at 60.
So invest as much as you can ASAP, and I’d recommend contacting Fidelity. They do a great job explaining your options and how best to meet your goals. They do charge a percentage fee on your investments, but it’s well worth it.
