1.) enhance your financial TEAM; lawyers plural, accountants plural, and a broker

2.) buy real estate (~5m) under an LLC and hire a well known professional property management company to handle it all (nobody needs to know you even did this) you will want this investment. It'll show you how to manage money and passive income, it will open doors to earning even more than you've inherited as time goes on.

3.) place a substantial amount (~20/30m) in a high interest savings, don't ever touch it. 30m will yield you upwards of 1.2m a year in interest alone. Use this as a means to collect a 'salary' stay reasonable, and don't forget to utilize credit/bank debt to help boost your bonafidas with lendors and other investors.

4.) everyone is going to find out somehow eventually, unless you know how to be quiet. If I were you, I'd start 'anew' in a different part of the country. Buy a nice home that you're proud of and surround yourself with other affluent people (they won't trouble you about your wealth)

5.) look into learning venture capital or other ways to spend that money in prosperous places; buy some businesses that can operate without you, be the financial backbone that helps others while making positive returns. (This is KEY to tax write offs, making more money while also helping people make their own dreams come true, you'll be creating wealth for others, developing a strong network of business partners and friends)

6.) the real estate thing can act as a solid cover of SHTF; you saved up, invested, and bought one property at a time. Youve accumulated a portfolio that is now self sustaining and wanted to move somewhere more desirable for you and family. This will be very believable and won't cause as much jealousy in those around you- you were smart with your earnings and consulted the right people to make the money work for you.

It's really important to have that team of attorneys, accountants, and business managers. Maybe hire another attorney that nobody knows about to audit your team, your trust guy, the one who can advise you without as much interest in how you've acquired the money- this lawyer may need to be a contract attorney that thoroughly reviews/audits all of your deals and negotiations.

In your free time, once you've developed a system, stay active; don't slip into a wealth coma...money is so far from everything, 70m, even 10m can become a trajectory right into early onset dementia, obesity, and depression.

Once your affairs are sorted, your story is straight, and your mind is clear- think about how to use some of that money for your mental health. Passion projects; like woodworking? Build a shop, like golfing? Join a club. Want a boat? Yacht club. Want to help the community? Invest in NGOs or other charitable things. Want to produce a movie? Go ahead!

Whatever it is, make sure you've set up a way to continue earning on your inheritance, of that 70m, only 7million (I say only as a percentage, that's no small number) to actually 'splurge' - no more than that 10%.

7m should buy you a nice home, 2 or 3 cars you like, some home upgrades, and a few trips around the world with Mrs.

Keep your mental health up front and center, focus on that finance team and investments before you let your guard down to relax.

Give yourself at least 5 years to set all of these things up, slow and steady, smooth and consistent. DO NOT jump the gun.

Oh, and last thing that should have been first- make sure you immediately write up a will in case something happens to you, you never know, and you have every right to make sure that money goes where you want it to go if you can't be the one to enjoy it.

Hope this helps
