Should I form a Nevada Corporation to hold money for investing or keep it in my personal account?

This is based on a chapter out of Robert Kiyosaki's Rich Dad, Poor Dad best-seller. He talks about protecting your investments involving real estate by starting a Nevada Corporation, yet doesn't mention whether that would be a good idea if you're looking strictly to invest for personal gain. The only appealing aspect to me is the fact that you could take the profits from when you sell and invest them further to avoid a capital gains tax. I'm not sure if the same law applies to securities as well as real estate.

For RE investment purposes,

Number one rule, don't put real estate in a Corporation. Never a good idea. One of the truly blanket "Never" rules around. Try LLC or LLP. You can elect sub S status if you incorporate but there are some restrictions and complications so watch out. Go LLC or LLP before Corp if you can.

You only need a Corporation or other limited liability entities for protection of assets, no real tax breaks and in some cases you'll pay more taxes. But think of any additional costs as insurance.

You won't save on state taxes if you don't live in Nevada.

And you won't save on federal capital gains tax if you sell. Doesn' matter if it's in a Corp or other entity, a sale is a sale is a sale and taxed. 1031 exchanges aren't sales and you postpone taxes no matter what your entity.

The problem with most of the get rich books I've found, if the subject they wrote about was so lucrative for them, why aren't they spending the time investing instead of writing?

I'm with your first answer, what taxes do you avoid when you sell? There isn't a provision for reinvestment and postponing taxes that I'm aware of. Someone is leading you down a weird path if they recommend something and can't explain why. I'd also be suspicious if they tell you inaccurate facts about taxes.

Why else would you invest if not for personal gain? Who's gain would it be? Why would you invest for someone else. Even brokers invest to make commissions which is for personal gain.
