on another note, I think there's nothing wrong with being an active trader, this is only matter of separation of capital, just get 5% of our overall portfolio for trading to manage risk I think it will be fine.
Be an active trader costs you a lot: time, health, and money as most of traders fail and lose money; but they have common things like wasting too much time and are not physically active enough so consequently they have health issues.
being active trading means it could help us accumulate more and more money on the side to invest, so the investment become faster in capital growth.
but just be sure that we can make profit using small margin/money first though otherwise we gonna waste money while grasping how market works.
Nope, trading is to get profit and use it for enjoying your life. Trading should not be connected to investment and if you think you are trading to get more money for investment, I disagree. As warned, trading is risky and can take money away from you, so it only makes your investment adventure more difficult, not easier.
I'd argue that swing trading and buying only when price fell off too deep is significantly less risky than daily trading and it's still considered active trader and this has helped me massively in building my portfolio.
I guess the fact that trading isn't exactly for everyone like as you said it can be mentally exhausting for people who are just impatient and can't endure seeing their capital tanked can be the main reason it's better for someone to not trade at all.
but for people who just got the grasp of how market works somehow, just occasionally buying the correction is fine.
I've seen many doing exact thing and it worked out for some.
