If you have that kind of mindset then it's different though there are different perspectives in terms of treating investment, if you are good in improving your knowledge and skills most of the time, trading might be a good place to use your money while in gambling even how good you are in anticipating the outcome luck still play big in terms of outcomes, though it's a self-explain for each individuals who participate either gambling or investing if they can't control their emotions and don't have enough knowledge and patience inside investment or business they are treating their money as risk in whatever opportunity they think to put it in and see the result.
Emotions tend to ruin the plans we have made and involving emotions in trading or investing can cloud the initial strategy. In trading, emotions are very influential because when control is lost, it can actually cause problems.
Investment and business are also the same actually because when someone is unable to control emotions we do not run according to the strategy that has been set well.
But in a certain capacity I also disagree if investment is similar to gambling because that is the behavior of people who do not understand the concept of investment with gambling.
In gambling, people hope for luck to make a profit, but in investment we cannot follow this pattern because without good analysis we will not understand how to invest properly.
Without good analysis and leaning alone with luck that's going to ruined your investment, either you are into business or to trading without proper knowledge about the industries that you are into, the chance of spending money and losing it all is very possible, but if you have good plan ahead and you know how to handle risk, there's a big chance that you may succeed and you may earn decently.
