Why not do both and see which is more profitable? I cannot under any circumstances advise taking on a day job at this point in time. Some research and basic math will unfortunately show you the truth. It's simply not worth it at the moment, just like pension or savings accounts. Besides, there are too many trained workers, without any other abilities or skills or the potential to acquire these, and who accept the easy way of taking what they're given. If you're one of them, go get a job, it's your best bet.
Of course, I have no responsibilities, so I can take chances at alternative opportunities and I refuse to live a mediocre life of survival with absolutely no chance for worthy achievements. However, I'm commited to risk, and I am not afraid to take chances (calculated), even if I die trying. Not many people are able to accept this. If you can afford to survive and can give yourself a shot at an acceptable life (you only got one), then go for it. Do research, absorb every piece of information you can and work for it harder than you ever have. That's a requirement. Other than that, It's your choice not an obligation.
If you get a job, also join the gym in January, motivated by the "new year, new me" slogan to donate gym owners some of your money every month for a year, after using it twice in January before giving up and unable to cancel it. Works a charm! Also, do not forget to "invest" a little in a new crypto coin like Squid or Shib with amazing potential and great hype online before it vanishes overnight and then give yourself a pat on the back and say it ain't too bad, it was worth a try, how could you have known, but at least didn't lose too much.
If you go day trading or poker, research them both like there's no tomorrow. For day trading, read everything about technical analysis, give quality signals a try, do some copy trading, use demo accounts (just like chips in poker but in trading it replicates exactly as opposed to poker where there's a huge difference between
real money and chips), create some trading bots, fail, then analyse what and why you've done what you've done. Generate some good patterns, leave emotions to your family, setup your risk management so you can profitably lose trades and stick to your strategy, no matter what. Then, put in some real money and dive in with your O2 tank, suit and goggles on not with a heavy rock tied to your ankles and your fingers crossed. If you're from UK, you're better off spread betting rather than day trading as it's classed as gambling, so you save the "rake"/tax for later poker purposes. For poker, play, read, play, analyse, play and adjust, lose your money and then come back more motivated than ever. Isn't this how top players got to the top? There can't be highs without lows.
One more thing, it's not what you do, it's how you do it. Be committed and happy with your choice. If you're used to dropping everything in life because of emotions, then don't waste your time and follow your intuition.
