Never quit or give up because of hard work. If you hate or are tired of your current job, changing jobs is not the most fundamental solution; it is useless for people who can't swim to change a swimming pool; the fundamental solution is to change their attitude. No job is smooth sailing.
We do all kinds of different jobs, and each profession has its own magical powers and its own difficulties. If you think that if you are wronged, you can solve the problem by quitting your job, or if you think that changing jobs will go smoothly, you are wrong, because there is really no job that is not hard and not wronged. Of course, the meaning of work is not only to meet our survival needs, but more importantly, we can realize our self-worth from it.
