Invest your money in real estate? (I.e. rental properties, etc)
Buy land? (Agriculture/grazing rental, land near developments for future project resale, recreational use, etc)
Play the market? Savings bonds? Etc..
Start or buy into a business?
What would you do so you had a steady yearly return from investments? Speaking in terms as if you had more than enough money and only used the money to pay property taxes/bills and get a slight/moderate return.
