To be successful in business, one has to work hard and should have a bit of luck too. Your horoscope is indicative of now working in a field which you are not interested in. Mercury is very weak in your horoscope and anything to do with Mathematics, Logic etc. do not suit you at all. Perhaps buying and selling products could make you a good business man provided you practice frugality which you are currently not comfortable with. Wearing stones will not help you in improving business.
Chances are you will do very well in business starting from 2021.
