True but at the same time it's important to only start with a balance you are ok with losing. I know there is no money that doesn't hurt losing but at least it shouldn't hinder your daily routine. My friends in past have taken loans to trade and it didn't went very well.
Yes, there is no money that we don't feel sorry for if the money is lost, but if it's already detrimental to our health, it's best to just stop trading. Or we can take an investment instrument that is more stable and has better long-term potential, for example gold. Many long-term investors have invested in this instrument, even if the profit is small, it does not affect their health. And also if we are not ready to trade on margin, you should avoid this type of trading.
Before trading makes someone to be emotional it means the person is not trading with the amount he can afford to lose or might be trading with the amount that he can afford to lose but still lose in a regular basis. If it is this cases all the person needs is to take a break and try to learn to understand what is the cause of regular loses and to the things in the right way. When their is constant loses in trading it means things are not done in the right way the way it should be done and the best thing for the moment is to give a break.
