Describe a person who is always positive

The most positive person I know is my friend Anvar, who has been my teammate in our university volleyball club for three years. He's a tall, cheerful guy who greets everyone with a huge smile, and I can't remember seeing him in a bad mood.

He shows his optimism in lots of ways. If our team loses a game, he doesn't blame anybody. He says things like, 'Great, now we know what to improve,' and then he suggests a small extra practice session. If the weather is terrible on the day of a match, he jokes that it will make us stronger. He's also generous with praise. When someone does something well, even something small, he is the first to say it.

I remember a particularly difficult period last year when he injured his knee just before an important tournament. He was obviously disappointed, but the next day he turned up to the games anyway, cheered from the bench, and kept a record of our points. When I asked how he could be so cheerful, he said that being worried wouldn't heal his knee any faster.

Being around him has a big effect on me. I tend to overthink things and worry about small problems, but his attitude is so contagious that I find myself relaxing. He's helped me to see setbacks as opportunities for learning.

I sometimes wonder if he ever feels sad, but I think it's his way of dealing with life, and it makes everyone around him happier.
