But I always came back to the fact that I can always do something different. I can drop everything and go back to where I grew up and just take an ordinary job.
Remember that there is nothing more important than your life and desire to succeed at a startup or in corporate America or anything else is just conditioning and not necessarily important at all.
Personally, I took a contract job recently where I can only work 8 hours a day. Its great to hang it up at the end of the day like a normal person.
There's nothing wrong with taking a break from struggling with a startup. Things will come together later. Its not supposed to be so hard anyway. There's a difference between intense creative collaboration and solitary unhappy struggle.
I truly hope this helps.
