“Today I will do what others won't, so tomorrow I can accomplish what others can't”
Doing jobs that no one wants to do helps you develop valuable problem-solving skills. Never be easy on yourself, be easy on all the others around you. If you are someone who picks and chooses posts, you are probably going to pick the jobs that are easier for you and that you feel comfortable doing. If you are less selective, yes, you may get more difficult jobs; however, this will allow you to master your craft and grow your skills in less common areas making you more valuable and versatile. You may end up developing expertise in areas that have very little competition. Of course, if the work doesn't make economic sense, it may be something you'd want to avoid; however, taking a loss now may allow you to acquire new skills that can help you earn more over the long term.
Completing undesirable work will help you build a reputation for being reliable, and you will be the first person people think of when they need help, like working weekends, night shift, or crawling under a neighbor's house to pull out a dead cat carcass that was smelling up their home. This gives you first shot at new jobs, promotions, essential duties, extra pay, and the best opportunities.
Throughout my working life, I've always taken whatever duties that others didn't want, and it has always resulted in positive benefits for me that were worth a lot more than the inconvenience I endured. I’d say that this trait has been one of my keys to success. Being humble and being willing to do what others don't want to do, takes self-confidence and humility. One particular assignment was working with aggressive and violent patients. None of my colleagues wanted these patients, so I volunteered to take them all. Occasionally the patients would hit me, or I'd come home with a few scratches, but after a while, I learned how to be more productive with them and became a specialist in this area. My income almost doubled over my colleagues. I was booked twelve hours a day, seven days a week, and I had patients on a waiting list to see me. This allowed me to raise my rates, expand, and be able to take more vacations. I also became so effective in the role that the kids rarely did anything I couldn't handle or help them resolve.
