Most investments require that you wait really long periods before you can collect an ROI (return on investment). However, there are some investments you can directly benefit from while you wait for your ROI. The following investments fall under this latter category. 

Real Estate

Real estate is, by far and away, the most readily beneficial investment you can make. If you buy intelligently, you can directly benefit from your purchase until you resell it at a later date for a profit. Think about it--you buy property, you fix it up, you wait.

Otherwise, you can buy residential property, live in it while you fix it up and then resell it. Another option is to buy a property, fix it up, and rent it until you can sell it. If you buy commercial property (e.g., office buildings), you can operate your business out of these properties until you can sell them, like some mobile office. Even if you buy just land, you can park an RV or camper on it and live there until you either sell the land or develop it and sell it. Regardless of the type of real estate you buy, you still benefit and/or profit from it in the short-term and again when you sell.

Roth IRAs

Roth IRAs are probably the second most beneficial investment you can make. These IRAs allow you to withdraw most of the money you put into the IRA, draw it earlier than the traditional IRA, and withdraw it without penalty so long as you do not draw any of the interest accumulated. Leaving some money in while taking some out allows you to continue collecting on your investment for the future, while you enjoy some of the money you have already put into it.

High Yield Savings Accounts

If you have a lot of money to invest (e.g., tens or hundreds of thousands), park some of that in a high yield savings account. Some of the best high yield savings accounts accumulate a ton of interest on the money you have in the account, and the banking institution allows you to draw that interest and live off of it while the rest of your money continues to collect monthly interest. If you have one of these accounts in conjunction with real estate, you could live in your own real estate purchases and live off of the interest from your high yield savings accounts, which is almost like living for free.
