Back in 2008, I faced an impossible choice — keep one company alive or let both collapse. So I did something unconventional: split my final $30M between Tesla and SpaceX, betting everything on the possibility that neither had to die. Both ventures were bleeding cash, the odds were brutal, and honestly, I wasn't sure either would make it. But looking back now, that split decision? It turned out to be the move that changed everything. Both survived that brutal year, and what followed proved why you sometimes have to go all-in on multiple bets when you believe in the mission.
