Now according to me, and this is my cosmology scheme, which I'm having trouble persuading the cosmologists about, is that when the universe is rid of pretty well all its matter, it in a certain sense forgets how big it is. Now that's a crazy idea, but you see if you don't have any mass around you don't have any way of scaling the size of the universe, and so it in effect becomes the big bang of the next aeon as I'm calling it – A E O N. So according to my scheme, the universe as we currently understand it, which is from big bang, and then there's this inflationary phase which I don't believe in, which is supposed to take place very, very early on, and then the universe has this more sedate expansion, and then it has another exponential expansion, and that's it. According to me, that's not it. It morphs into the next big bang.

To the extent that we ignore this, forget about it, become complacent, or believe that it is so infinite that it can take care of itself, we are in trouble.

You see, researchers have coined this term "color blindness" to describe a learned behavior where we pretend that we don't notice race. If you happen to be surrounded by a bunch of people who look like you, that's purely accidental. Now, color blindness, in my view, doesn't mean that there's no racial discrimination, and there's fairness. It doesn't mean that at all. It doesn't ensure it. In my view, color blindness is very dangerous because it means we're ignoring the problem.

There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can’t afford to pay off their loans, let alone start a business. Look, I know a lot of entrepreneurs, and I don’t know a single person who gave up on starting a business because they might not make enough money. But I know lots of people who haven’t pursued dreams because they didn’t have a cushion to fall back on if they failed. We all know we don’t succeed just by having a good idea or working hard. We succeed by being lucky too. If I had to support my family growing up instead of having time to code, if I didn’t know I’d be fine if Facebook didn’t work out, I wouldn’t be standing here today. If we’re honest, we all know how much luck we’ve had. Every generation expands its definition of equality. Previous generations fought for the vote and civil rights. They had the New Deal and Great Society. Now it’s our time to define a new social contract for our generation. We should have a society that measures progress not just by economic metrics like GDP, but by how many of us have a role we find meaningful.

I communicated that I wanted to skip press conferences at Roland Garros to exercise self-care and preservation of my mental health. I stand by that. Athletes are humans.

I feel uncomfortable being the spokesperson or face of athlete mental health as it's still so new to me and I don't have all the answers. I do hope that people can relate and understand it's O.K. to not be O.K., and it's O.K. to talk about it. There are people who can help, and there is usually light at the end of any tunnel.
