Each day should be lived to the fullest in ways that you stay true to yourself, and be happy. Waiting for tomorrow to live is silly when we don't have any sort of guarantee that we will even awaken each day.
I have seen people who appeared otherwise healthy, die of heart, brain, or other issues, in their sleep with no warning. It's devastating, and even worse, I've known people who were murdered before getting a full fill of what their lives had to offer. Don't be afraid to be yourself and do what makes you happy. Whether we live just once or many times, we need to make the most of each day-life is more than just work and play. Spend money for necessities and experiences and you will enjoy life the most.
