What's sad is never having tried because you felt at a certain age that it was too late for your success. Dreams should have no age limit. The good news is that it's never too late to prioritize yourself.
At 30 you are still adolescent, at 40 a grown man; nowadays men of 50, 60 or even 70 are in early, high and late middle age. At 80 you start really aging, but 90? There is no real label: you are an antique.
Take that jump into the deep end of the pool and start paddling as fast as you can. You'll find that if you follow your heart's desires and you believe in yourself, it's never too late to live your dreams.
