It takes three years to become a design master and five years to become a master, but it depends on talent to become a master. If you want to start your own company, you will have strength in five years, but the production and learning of the company are different and very boring. There are many trivial things to learn about construction, management and customers.

The key lies in technology, and the key lies in not doing your homework well, and whether you can gain insight into the opportunities in the game with the dealer. So your choice lies in your life orientation.

When you are your own boss, you can't sell. You should design well, master the technology and make a living first. Wait until you become a master designer, and then work hard in the direction of the boss.
