Honestly, making trading your only source of income is not a good idea, and it is very hard to find someone who can solidly rely on trading for survival.
Diversify your income resource is good because it helps you to avoid terrible time when you can not have any income at all. When one income resource is bad, you can have one or two other income resources for using.
Many of these rich traders that we see and hear about on social media already have different sources of income but there just just talk about it.
Rich or poor traders, can say many convincing things but if they don't show proof of trades or share market signals, predictions that become accurate later in actual market, you can not trust their words of self-claiming as good traders.
"In God we trust, all others must bring data" is what you should do in life, to verify things, not automatically trust anything.
