The best way to use your money is to make your life easier and free your mind from small worries. Don’t stress about the price when you book a ride or buy groceries. Go to that concert. Book that vacation. Life feels best when it flows and you’re present in the moment. If your spending causes more stress or overthinking, it isn’t really helping. You can't take your money with you when you die, so focus on enjoying life now instead of just saving for a future that might never happen. You can always earn more money.
