There are two conflicting sets of thought about how to approach entrepreneurship (and life in general).
The first set of advice is that you have to hustle, you have to be always-on. If your competitor is working 50 hours a week then you need to work 100 hours a week. If you are not monitoring social media in real-time, 20 hours a day, then you will miss opportunities. You need to throw yourself 200% into what you want to achieve.
The second set of advice is that you need balance. Being burnt-out is no way to find success. Missing out on family, and friends is not worth the price. You need energy from rest to keep moving ahead. True success comes from a life where your work, family, sleep and perhaps spirituality are all balanced.
Both options have successful people as examples. Neither are right or wrong for everybody. You need to pick the one that works for you.
But don’t judge people who choose the other path. They are doing what feels right for them.
