Brief
I wanted to take a sabbatical from work to learn Aerial Circus (as you do). The only problem was trying to convince the powers that be to let me take 6 months out and still have a job at the end of it.

Solution
I created a typographic letter, to explain my madness and remind them that I'm a pretty creative guy to have around. It worked and six months later I was performing on the Southbank in London – pretty cool. (And I still had a job).
