Jimmy has a long list of jobs to do. Some are quick and easy, so he does those first.The others are so difficult Jimmy puts them off because he hates those jobs. Soon,he realizes something. He can't put them off forever. So he tries to see them in different way.
First, Jimmy stops using the word "hate". The jobs aren't so terrible after that. Then,he thinks about the reasons for doing them. When Jimmy's mind is ready, he starts work. He takes his list of jobs and puts them in order from the most to least important.Jimmy chooses the top one and starts. He works a while and then takes a short break. That helps him keep going until he finishes the job.
Everything gotten much easier ever since. When that happens, Jimmy feels good. That good feeling helps Jimmy succeed.
