The right approach and the right mindset is to make trading a part-time job that is useful to supplement your income from the main job, and even if for example you manage to become a fairly professional trader by always being able to make a profit or when you are already in a situation where your profits are greater than losses then I think at that time you can think of a new plan, you can quit your main job but on the other hand you also have to build another place that can provide you with income such as maybe a business or other things that can provide a fairly certain profit.
You're absolutely right. Maintaining a main job while trading on the side is a practical approach.
Keeping your main job ensures a steady income, which safeguards your ability to meet basic needs without the pressure of needing constant wins from trading. It's a wise strategy to treat trading as a supplementary income source until, perhaps, your trading profits are consistently outpacing your losses.
It would really be the most practical approach rather than on going full time. It would really be just that only viable if you've seen that you are already a profitable trader on which you would really be making up some decisions on going full time but since this is kind of skill that cant really be easily obtained then it would really be that hard for you to achieve such condition and not all becomes a successful trader
on which it would really be better that you should really know on how to make wise decisions because going directly on going full time trading then you wont really be able to know whether
you would really be sustaining or not. We do know that this isnt something that makes out assurance and not something that could really be easily be obtained.
