Money solves (some) problems, specifically those which can be solved by money.

Money provides some optionality when it comes to material comforts and experiences that can be purchased.

Life is easier with money and lack of money almost always causes stress, anxiety, and worse outcomes.

All that said, you can't buy happiness or fulfilment. The closest you can get is the removal of financial stress. Which, trust me, can be a big relief.

But you won't find meaning via the removal of a stressor. You'll still be you. If you were happy before you had money, you're in good shape. If you're like most of us and feel unfulfilled, money is not going to help that.

Money is good for when you need money. But it won't make you happy.
