Do you feel that there isn't enough free time in the day to do everything you'd like to do? Realize that everything you do is exactly what you have chosen to do, and therefore you should do it with all your heart. There is no "free" time, just time. You can either spend it in joyful awareness, or spend it wishing you were doing something else, building feelings of resentment. It's a matter of committing yourself to whatever you are doing at the time. Either do it with joy, or don't do it.
I used to resent doing housework, especially washing the floors. Then I realized that I choose to do it, no one is forcing me to wash floors. I choose it because I want clean floors. Why should I resent doing something that I choose to do? Now I put the radio on and practice singing while washing. It becomes a joyful chore.
I often hear people complain about having to take care of their parents, grandparents or children's needs. "I have to take Johnny to karate and then help him with homework, I have no time for myself." Well, actually, the time you have with Joey in the car is time for building your relationship. The time you are waiting for his karate lesson is time you could be reading, meditating, or catching up on phone calls. The time you are helping with homework, you are fostering a better understanding of your child and nurturing his academic growth. What part of these examples is wasted time? All of it, if you are doing it with resentment in your heart.
You never have to do anything. What you do with your time is your choice.
Be free to experience your time with awareness and joy. Don't be a victim of your ego mind telling you that you could be doing something else instead. These types of thoughts create unease and stress. Realize that you are free to spend your time however you choose. Time is always free, are you?
