I've been watching all the tributes to Chadwick Boseman and people saying it's so sad he suffered in silence but that is their assumption and probably how they would have handled the circumstances had they had the same fate but for all intents and purposes, for Chadwick, it appeared it was just the opposite.
The people that he wanted to know knew and in the four years after he got his diagnosis he made several hit movies, got married, and became a legend for many decades to come. He is literally a legacy superhero. He could have been depressed after his diagnosis and disappeared and quit but instead, he went even harder having many surgeries in between the filming of those movies. He squeezed a lot of life in those 43 years more than most people will do in 90 years as an entire combined community and it's evident he wasn't dying, waiting, or feeling sorry for himself … he was actually LIVING and making the most of the time he had left. That's incredibly powerful in and of itself. As life is not promised or guaranteed. Time is all we have. The question is what are you going to do with the time you have left.
