Getting Thrill points:

You can get Thrill Points for doing almost anything, such as running a mile, 
riding a coaster, painting a stall, etc. If you get enough Thrill points, you 
will advance to the next managerial level. A good way to earn Thrill Points is 
to pick up shiny signs that can be from shrapnel to an anti-Thrillville ad.
