What does “having it all” mean to you? Throughout my twenties and thirties "having it all" meant having money, more fame and more senior titles. But in the past ten years, “having it all” has meant knowing when I have had enough. This means knowing the extent of what I can handle and what effects my life and my emotional wellbeing.
Why did you chose to not have a child? I chose not to have a child because I saw how much my mom worried about me and how much money she spent on my education. I also like to sleep. So the benefit of being married without kids is that I can sleep as late as I like on weekends. Also, I can quit my job to travel overseas when we want to. I can have more freedom to pursue our personal interests and be less concerned about our family's future.
What gives you energy? When you understand your own mind, you understand your own behavior, which helps you understand other people's behavior. Therefore, you will spend less energy figuring out people's problems. When you have more more energy, inspiration will come easily.
