Got this pic from TMZ, this was taken 2 days after he sent his resignation letter to Apple. I already assumed that he quit because of his struggle battling cancer since 2004, to be precise, a rare type pancreatic cancer called islet cell neuroendocrine tumor.
He never gave up that easily… I admired his determination and struggle to keep up and move Apple to its peak of glory, in the same time battling cancer. Up to a point where he can no longer meet his duties and expectations as the CEO of Apple. There are other speculation why Steve quits his duty, but I leave that to you to search up on the interwebs.
As for now, Apple is now led by a new CEO, Tim Cook. All the best for Apple in the coming years.
I have made some of the best friends of my life at Apple, and I thank you all for the many years of being able to work alongside you. ~ Steve Jobs
