The difference between kids at a playground and a startup is that kids don't have to worry about anything in that moment. As a startup founder you usually have to worry about money (personal and in the company) which is technically the only important thing at the end of the day.

Startups are hard. I agree, it's not a bad thing and something being hard can also be the challenge that you are looking for.
