Hustle or Work-Life Balance ... That topic has always been keenly debated. In my personal experience and opinion, it all boils down to the reasons why you are starting your entrepreneurship journey.
Are you starting out because you are tired of the pressures of keeping a job? Tired of the constant work pressures and wish you could have more control of your time and activities?
Or are you starting out because you have a brilliant idea/capability that you would like to monetize?
Or are you starting out because you have a brilliant idea that you would like to touch and impact as many people as you possibility can, and hopefully be able to improve their quality of life?
Different goals result in different approaches.
If you are goals are aligned along having a work-life balance, make sure you and your team understand and agree on these goals collectively. You need to be sure that everyone on-board understands that the journey isn't to make the most money, isn't to touch and impact the most people but rather to achieve financial freedom and a work-life balance for everyone. If that's the goal from the on-stead, I see no reasons why you cannot be a work-life balanced entrepreneur.
Wishing you all the very best in your entrepreneurship journey.
