How many hours a day/week are you working on your business?

I started my company two years ago in my cousins garage. After a LOT of hard work and an average 10-14hr days, we’ve grossed over $1.6million this year with a profit of just over $385k.

I feel pretty good about this but I’m curious how much other entrepreneurs are working. Is a 50-60hr workweek normal while building a business?
