Episode notes
Relentless Grind Built His Comedy Career
- Don performed an extraordinary grind early on: 323 nights in one year and continued heavy performing for five years.
- That relentless AB-testing approach (keep jokes that work, discard others) built his act and led to being chosen for the San Francisco comedy competition.
San Francisco Contest And A Career-Making Commercial
- At 32 Don made the San Francisco comedy competition and booked a national United Airlines commercial, which gave him the confidence and financial cushion to quit engineering.
- The commercial ran widely and Don saw it as a universe-sign to walk through the open door.
Control Expenses When You Pivot Careers
- Do manage costs tightly when switching careers; Don didn't lose money his first year by drastically cutting spending and travel-hacking.
- He booked every week, leveraged improv training and club work, and relied on plentiful 1990s club opportunities to stay busy.
