Yes, I also did face this kind of problem, People just keeps giving you advice. Earlier I was in gambling and people say you wasting your time, you'll lose all your money. Instead of gambling, you should invest in trading and so on. But I took a risk and did get a good amount of returns from there. The thing with life is you have to face these people almost in all fields of life not just in terms of business but almost every field wheater it is lifestyle, education, luxury. So keep yourself clear and Do what you think is right after proper analysis
Specially for trading.
