$25,000 to my name, how to invest wisely?

Hello, I am 26 years old & I have saved up about $25,000 over the last year or 2. I want to invest into my future, I want to make sure I am making the correct moves with my money, while I am blessed to be making this much. What stocks would you guys recommend to buy and hold? How much should I be putting a month? Any help would be appreciated
