You've already had some good advice from this page and you'll get a lot more. And, I suspect you need it.
1st of all and most important, what do you want to do with the rest of your life? You've worked, traveled, probably with a nice expense account. Now you need financial advice but, more importqant, what will you do every day when you get up? At age 50 you need to think about it. Spending about 3% of approximately 1 million won't allow you to spend big and travel. So, would you like to consult, work part time, do charitable work every day? Most important is to plan how you will enjoy the future based on how you enjoy whatever you do most days.
Now on the financial side......you should consider a financial planner paid by the hour that doesn't want to sell you anything and can look over your assets. I suspect many will tell you to place most of your assets in low cost index funds and manage them yourself. I use Vanguard and Fidelity....Vanguard is the cheapest and I like them best. I read Money Mag, weekend WSJ and Barrons every issue. Now, in most cases these publications confirm my FI plan. Truthfully, I'd be concerned over FI with 1 million at your age.....but that's me....I earned good money, like to travel, and spend far more that 3% of 1 million and my SS.
You have a ton of great options. You have investments, obviously you have skills, and you have the opportunity to do whatever you would like to do.....good luck.....Enjoy your good fortune.
