When you cut grass with a scythe, you have to pay careful attention to the way you hold the instrument, the angle of the blade on the grass, and the way you stand. You have to coordinate the movement of your arms with the rhythm of your breathing and be aware of the activity you are performing.
These are all acts of mindfulness; they will help you complete your task without getting tired or losing your breath. Apply these acts of mindfulness to all your tasks to achieve similar results.
When you begin to practice mindfulness at all times, you will also discover happiness. Think about it this way: When you do not have a toothache, you are not aware of the happiness of a non-toothache. When you practice mindfulness, you will be aware of your non-toothache and thus be happy. Remember, when you practice mindfulness in the present moment, you are working toward peace in the future.
Appreciate every day.
