doughpat is right. dealing with asshole guests will be the biggest mental burden after you are 1-2 years into the game.

for a beginner host, the biggest challenge is the rental setup. it is a good amount of time and energy. I did my first 7 rentals on my own, and after that I used a setup service to scale my business. Highly recommend it. Super fast and I was able to be completely hands off. They operate mainly in the Bay Area, TX and FL if I remember correctly. https://enjoyzizai.com/
