First of all congratulations on entrepreneurship journey and we are very happy to note that things are going well.
When it comes to work-life balance, especially for self-employed/entrepreneurs, it is crucial to set boundaries and have clear priorities.
You would need to take your 24 hours and divide it into office work, personal life and self-care.
Please note that taking time away from personal life and self care is only going to put you on a fast track for burn out.
Success means a lot to everyone including you but there are no shortcuts, you can't rush to your business goals, especially losing yourself in the long run.
Time management, daily planners, stop checking work emails after 8:00 pm, setting daily goals, waking up early, managing health and fitness are a few key steps that would help you in finding a balance.
I recommend, you read 4 Hour Work Week by Timothy Ferriss.
Remember, everyone has the same 24 hours. The magic is in making optimum utilisation of this resource called life.
Best wishes to you.
