Success means at the end we can get the profit but a lots of people including me will not get the success at the end because overconfidence without investment is made the confident to a negative way of investment it definitely leads to getting lost only at the end.
The question is, when will the end? Although, for example, today we are lucky enough to win some money through gambling, there is no guarantee that we will be able to defend it in the next day. Success can be pinned only to those who already leave gambling completely in a good way (with profits).
