I don't have anything to write, you have to watch it yourself, experience everything and understand it yourself.
to finally found your own answer for "what is your reason to wake up everyday ?" just as how every character in the series to find their own despite every loss they had.
I recommend you to watch from the season 1 to have full experience, and just enjoy the journey. It never was about winning the games, everything that have gone are meant to be gone, what all matters is what after it. do you want to live on or stay.
warning for those currently struggling in their life, you find yourself think back, and repent about how you've lived your life.
