Probably, those who start investing has already aware of their position and the consequences awaited them. As it involves money, either small or big investment it corresponds to risk. That is why we have to invest our money only the amount that we can afford to lose and we don't have to force ourselves if we are not prepared and most especially if we don't have any idea about the thing we invest in. In that case, it is to expect that losses are near to you, not profit.
You are right about this. A calm attitude in investing is also an important part. I often hear complaints about losses suffered. In my opinion, investing a small amount first will save our money for later investing in large amounts.
