Basically, I agree that trading is not a lifetime job, because trading has a lot of risks. I also suggest for people who want to try to focus on trading to have other income, whether from work or business. However, when you are successful in trading, don't forget to develop the business you have, or build a business to earn other income. I think that trading is not suitable as a job for life, but it can be an income that can encourage us to achieve financial freedom by using profits from trading to support the businesses we have which is suitable as a job for life
to be trading for entire life, definitely can be done, the question is, are we really have the will to trade until our entire life? considering that trading is exhausting activity where having mental stability is matter a lot.
many people don't like trading as a job for the lifetime because its just not really an activity that they are looking up to.
they just want some good easy to do job when they are already old, with trading, even if we are making money and im talking about good money, there's still a big chance that within few times forward we might lose a money due to volatility, definitely can't do that when we are old enough.
Trading is not a main job that can always provide income, the possibility of risks that cannot be fully tolerated is always a problem that makes people reconsider their intention to make it a main job, and this is why people usually prefer to make trading a side profession to increase their income. And I think this is actually everyone's choice, you have said the right thing that trading is not always easy to do, because it is very draining on our minds and also mentally when we analyze a market.
It is true that when a person has entered old age then it is certain that they will experience a decline in thinking and remembering things so of course it is likely that trading will be increasingly difficult to do because the situation is not possible and most likely we will probably experience more losses than profits regardless of those of you who are experienced in the world of trading when you enter old age.
