Tips for job-hopping
Do not take changing your job as a way of seeking promotion and more pay. Although quite a few people manage to do so, their number accounts for a small proportion of job-hoppers.
Do not blindly follow other people in job-hopping. There are people who changed their jobs only because their friends have done so several times and they want to follow suit. Most of them ended up missing their old jobs, only to find there is no way back.
Do not envy high pay in popular professions. You should remember: Your personal gain is always decided by your contribution to the company. If you want more money, you have to earn more for the company in the first place. You have to think beforehand whether you can agree with that kind of lifestyle. After all, there is no free lunch in the world.
