If you experience something early, you have memories of it for the rest of your life, which is very long span. If you experience the same experience later, you have less years to hold the memory. So all else being equal, living the good life while young is better than not. Clearly this could backfire if one goes way over their means like over spending, hence the cautious notion of delaying gratification. But generally, its good to have good experiences earlier than later, so long as there is some balance. Reminiscing is incredibly important. It's simple mathematics. Time is finite, so earlier memories last longer. Opinions?
