Do we have the luxury to enjoy the moment as a single dad or mom

As a single dad, I do not have the luxury. When Amy was little, I got to have attention all the time to her. I need to read her books. I need to feed her. I need to get her on bed and until she felt asleep. When she got asleep. I was exausted. I only have the luxury to call my friend to share what had happened today.
Now Amy is growing up. She can do a lot of things by herself. However, I still do not have the luxury for myself. Everyday afterschool, I take her out to play ground for about one hour. I took her out for  a variety of activities, such as skating in winter, swimming in summer, violin, Chinese, gym etc. I know those activies are critical for her development. Whenever I go, I have to take Amy with me, such as to go to a Toastmaster meetings, NSA meetings or so.
My friend has a son who is bigger than Amy. She does not have the luxury either. If she shift her attention away from home a little bit, her son will play game all the time. Some time he even does not want to go to school.
Single dad, single mom, you do not have the luxury now. However, you will be rewarded for your effort when your son and daughter grow up.
I would like to say that we are not enjoy the moment; we are enjoy life. We are enjoy the life as a dad and mom.
