I always thought that, if you didn’t like the work, don’t do it. There were so many job opportunities before, you could find something that you truly loved.
Now, with so many unemployed, it could be argued that just working is important. Not to be selfish. To provide for you loved ones, your family.
However, it holds true that you must love your work. If you can’t do the work you love, love the work you do.
