Most of my ukulele heroes were traditional players from Hawaii, like Eddie Kamae and Ohta-san. There may not be uke stars in popular culture, but there are certainly pop stars that play uke - George Harrison, Eddie Vedder, Taylor Swift, Train, and Paul McCartney.

Bill Gates recently picked up the ukulele. And Warren Buffett is a huge ukulele fan. I even got to strum a few chords with Francis Ford Coppola. It blows my mind that these people, who have everything in the world they could want, have picked up the ukulele and found a little bit of joy.

One of the biggest things that happened for me was YouTube.

When you play guitar and strum, you're using biceps and triceps to move up and down. I realized you could just turn your wrist, your forearm, using smaller muscles in your arm that are much more efficient and much quicker.
