I personally feel that in fact, since it is an industry, there must be a market for him, demand will be generated, it seems that the promising industry is nothing more than the current talent supply, maybe after a period of time, everyone has gone and oversupply is possible, but in fact, as long as you are mature enough, nothing is no prospect, Similarly, there is almost nothing to say that you can't learn, you can only say that depending on the individual's talent for this to determine the speed of learning, but as long as you seriously learn, you learn one year, you can try to teach the unlearned, you learn five years you can teach one year.
