What non-financial knowledge/skills have you gained, ever since you started investing?

Invest in what you understand (circle of competence). Don't invest in what you don't. If you can't explain what you're investing into within 3 sentences or less to a friend who has 0 knowledge about what you're buying into, you may not fully understand the investment.

Don't act on a hot tip, do your own due diligence. One of the biggest mistakes I made was listening to my stock remiser who pitched penny chips and promised the moon. Always do your research.

Don't time the market; Insiders, fund managers, professionals who have access to information readily way before you do are already in it. Dollar cost averaging into solid businesses you believe in. Big boys are the ones who manipulate the share prices, don't act emotionally. They have unlimited resources to burn, we small frys don't.

Learnt to read more news regarding lots of things and it's always better to be knowledgeable

I think the art part of investing is coming in, slowly, but surely, over time. Whether to wait for one more day before entering, or transact immediately.

After investment is made, how to deal with it when everyone around is sort of losing their heads. How to say, "nope, I'm not chopping my own head off."

And in the case of things heading south, to have the guts to say, "I've made a mistake. Cut loss."

💎🖐 market up or down. Be emotionaless and hold/buy more.

Dont believe in media.

The best investment strategy is DCA, buy & hold
