That is an awesome comic you point to!
I learned to juggle in college and by the time I graduated with a BS in math I just wanted to perform. So I did street juggling, taught juggling classes, took up clowning, did some small gigs, then went to RBBBCC and toured with Royal Hanneford for a year. Then I really wanted to be a math teacher. Took the GRE and scored high enough to get free tuition and a TA position at FSU, which also has a student circus.
Fell in love with math at grad school and stayed on for a doctorate. Circus is far in the taillights now, but I continue learning new things and making new things. Very much into math art now, of all kinds, and have made digital art, print, videos, sculpture, jewelry, music, drama, literature and poetry.
Running my own math creativity center now. Don't know what the next career is, but there is still time...
