While money doesn't buy happiness after a certain point, it can certainly improve your life while you're struggling. In fact, having just a little more money can change your life and who you are.
Imagine not having to worry about every last little expenditure? How about being able to pay for unexpected bills without going through a personal crisis? Or being able to buy quality items instead of the cheapest items because you have no choice.
But most of all, how money can alleviate stress, worry, and depression almost instantly. And it really doesn't take much more cash to do that.
For anyone living a miserable, broke existence, this should be a top priority.
You have one life, make it count.
