1) https://www.bogleheads.org/wiki/Managing_a_windfall (the Bogleheads community is great)

2) Read this book: https://www.amazon.com/Investors-Manifesto-Prosperity-Armage... (or anything else by Bernstein, for that matter)

3) Try to steer clear of people/firms who want to manage your money for a hefty percentage fee. They're one step above crooks, sometimes not even. In the wise words of John Bogle, "you get what you don't pay for."

Good luck, and congratulations!

Read anything by William Bernstein or Jack Bogle.

You can start here with Bernstein: https://www.amazon.com/Investors-Manifesto-Prosperity-Armage...

Or here with Bogle: https://www.amazon.com/Little-Book-Common-Sense-Investing/dp...

His newer book "Investors Manifesto" is even better and incorporates the recent recession. As always, it's brilliantly structured and easy to read.
