Day trading is good and youre being your own boss by doing that. But just dont forget that day trading is not meant for everyone. I do know some people claim they rely on trading alone. Dont do such because you see others doing it,, be truthful to yourself and do it the way you can. You can still have a job doing and still have trading as a side job,, that will work perfectly fine.
If you know the trading and have experience day trading is really the best job as you can earn daily and enjoy profits irrespective of whether market is going up or down . Though it involves risk but you are rewarded in a great way as well. So take decision wisely .
