My birth date is 06/26/1976. My wife's birth is 06/13/1978. Questions about investment

Well, my first suggestion is that you should make an expense plan for your life. If you do not control expense, you will always use your money up no matter how much you earn.
My second suggestion is about investment. Do not expect too much in those high reward investments, they always have a high risk also. A firm investment would be better for you. This is a good year for you to have investment. If choose correctly, you will have a considerable savings.
