Anyone who likes to listen to others chatter for no reason proves that you cannot do it. Anyone who follows others proves that you cannot do it. Anyone who likes to resist orders proves that you cannot do it. Since you cannot do it, why not learn? Learning may cost you a little money, but the tuition you pay to the market and the so-called teachers is much higher. No need to think about it; learning costs definitely less. If you cannot do it, then go learn. This market is relatively fair; if you can do it, you can make money. If you cannot, you won't gain anything.
