Play like a child. Study the behavior of children and you can learn lot from them. Think your childhood days and remember how you were happy. When we become adults, little by little our ego takes our happiness away and we become serious people.
Children are playful. They want to play at any moment. Anything they find they use as a toy. To be playful you need a child like attitude.
If you do not have expectations and live in the present moment like a child, you can live happily. Always you can be playful. Playing is another way to learn. You can play with whatever you have.
See the children and learn from them. They have no other work than playing. They enjoy life. If you are serious and take life seriously, you have no time to play. What you have to do is to relax and enjoy life like a scoop of ice-cream.
If you enjoy the work you are doing, then you improve the quantity of work as well as you can do that work more efficiently and more creatively. That type of work gives you delight and happiness.
When you go to office or factory, go there like a player going to the playground. Do your work with playfulness and you will improve your performance. Give permission for you to enjoy whatever the task you have in hand and be playful. Always be an enthusiastic player
