We often avoid tasks because we find them too big, too overwhelming, too tiring, to difficult for us or taking too much of our time.
Breaking a task into several smaller tasks can solve this problem. Then, each one will not seem so difficult or intimidating. Instead of having one big task, we will have a series of small tasks, which do not require too much effort.
This approach can be applied not only to tasks, but also to goals and everything else we have or need to do. This will tend to melt much of the laziness and inner resistance we often experience.
