As the founder of a health tech startup and mother to 2 teen boys, I have lived this every day for the last three years. All the experts have provided excellent tips on time management and creating boundaries. I will echo that being strictly disciplined with time management is very important along with the more difficult task of making sure that every task is one that moves the needle and not just busy work. From one parent to another, let me assure you that you will make mistakes and will miss important events in your son's life. But running a startup can allow you to spend more quality time with your child, than working a traditional job. Make a decision now on your 90 day short term goals and over all 6 month goals. You will have to revise repeatedly. Never beat yourself up. Look at each day as an opportunity to do a little better. Take care of yourself. If you don't take care of your self, you will not be able to run your startup or take care of your kids. Enlist help from your partner or friends. Part of being a CEO is building a team and that includes people who can help with home and family obligations. If you are passionate about your startup and your family, you will find a way to achieve what is really important to you with respect to each. Finally, don't listen to the negative voices or well meaning advice from friends & family. Take expert advice with a grain of salt. Only you know yourself and your situation. The greatest advice comes from within yourself. Good Luck!
