People go crazy in their 40s. It's high school all over again because of social media. Unfortunately, this spending creates a lot of debt.
I went the other way and became a saver and investor. Now, I am retiring at age 42 and will not need to work again. Oh yeah, my wife is doing the same.
How did we accomplish this feat? In one word—income. The more income you create, the better retirement you can build.
Your 40s are about becoming an income investor. You can generate so much excess income that you won't know how to spend it.
And the best part is that it comes back next month; it's like a regenerating bank account. Your 40s can be memorable and fun; however, they must be full of income first. Good Luck!
