If you are interested, you should also combine it with reality! That is, interest belongs to interest and reality belongs to reality. Don't swing from side to side If you really want to do this, don't be afraid of wolves and tigers. Just because you're afraid you can't find a customer doesn't mean you can't find it yourself, right? If you really feel pressure to find customers, you can choose to do machinery. You can learn technical analysis in your spare time, or you can accumulate something, accumulate technical support for your future investment and accumulate funds for the future! Kill two birds with one stone!
