We all have jobs we don't want to do, and we deal with that situation in a variety of ways. We may procrastinate or simply not complete those jobs at all. We might hire someone to do those jobs, or we might just push forward and get those jobs done.
I have a big list of undesirable jobs to complete at the moment. The jobs are of my own choosing and I know that to complete those jobs will bring me and others some satisfaction.
So how do you get up the good energy to get those onerous jobs done?
First, define the rationale and purpose. Why do you want to do those jobs and what purpose will those jobs serve. Today the jobs I'm resisting have a lot to do with healthy sustenance and happiness for people I care about.
Then make a plan--how will you get those jobs done in a timely, positive manner. Create a timeline.
After that, just do it, and finally enjoy the result of doing those tough, but meaningful tasks. Onward.
