Apprenticeship can be said to be a thrifty way of learning. Most people think so. They can kill two birds with one stone by learning technology and making money. But this way of learning may be the most expensive. Everyone has heard the saying "teach an apprentice and starve a master", so when you become an apprentice, the master will not give you the essence easily, and it will take a long time for you to do odd jobs, even if you learn useful skills. Time is money. If you have time to do odd jobs, you might as well go to school for intensive reading. Learn something more professional and time-saving! Go out and find a well-paid job, and you don't earn much. The pros and cons of this are still to be measured by yourself.
