Misconceptions and the hearsay that they've heard about the business/investment, so instead of taking time to learn things they just push their ways and start their journey, most of those who lean with luck ended up losing a lot, and the experienced that they've got push them away to this venue, it's very important to know the basic and along the way start improving yourself in terms of this investment.
You are correct in that there are a lot of people that go into trading without approaching it as a skill based pursuit. They use chance and feel, rather than adequate enlightenment and plans, which make it gambling. Trading is about discipline, patience and a constant process of learning yet most ignore the step by step doing and run out of money.
