What do you consider the most intimidating part about starting a company?

People leadership is hard - or at least doing it well is the hardest part of leading a company to success.

A robust plan

Health insurance.

There should be another option "All of the Above" :D but if I have to choose just one, it's definitely trying to get by with little to no salary until a steady revenue stream is achieved. All other challenges, in my experience, can be overcome, no matter how daunting. And even after there is a steady revenue stream, we founders oftentimes try to survive frugally to ensure there won't be unforeseen hiccups (like the pandemic, for example, which made things a lot more unpredictable) because, no matter what, the one thing we cannot take chances with is the teams salaries, and we should ensure that does not get affected.

Ideas are often easy, even really good ones. The courage to head off without a safety net is the biggest issue for me. I've been working since I was 11 and the idea of being without a salary for 12-36 months or longer as I get a company started is terrifying.
