See work and play as one and the same. Allow no separation between the two. What you do as work is also play, and vice versa. However you make your living, whether you are a surgeon, a truck driver, or a musician, see your job as a game, as a playful activity that you would do even if you were not being paid to do it.
If you don't feel this way about your job, concentrate on the smallest units of your work. Someone who works as a salesperson in a store does lots of little things. He dresses to play a part, asks people if he can help them, puts merchandise in order, makes casual chitchat with customers, answers questions, gets to trade clothes for money, works a cash register, writes out a receipt. Any and all of these activities can be seen as productive as well as playful.
Whatever you do, whether you use your hands, talk on the telephone, write, arrange things in a beautiful way, or take apart machines, a child does the same types of things. The only difference is that the child knows that what he's doing is play. To him, it's fun, and it's exactly what he wants to be doing from moment to moment.
The difference between work and play is an attitude, a thin line that exists only in your mind. Cross over frequently. Obliterate the distinction, and the heaviness of work can be replaced with the lightness of play for long stretches of time.
