3 words that describe the peaks & troughs of founder life?

There is so much out there on what life as a founder is like but I want to sum it all up into 3 words. What are the trends? What are the common experiences?

Demystifying the founder experience is something I am super interested in. Why? My thesis is the more we know about something, the less scary it is and we can all make better choices. When it comes to founding a company, helping folks quickly understand what life as a founder is like helps build empathy, intrigue etc.

So what are your three words?

Mine: Brutal | Lonely | Exhilarating
