OP meant to say was day trading isn't profitable in the long run, you may be earning today with your day trading skills but once the cycle of market change then that's the time you will start to question your ability in day trading. That's why OP said that 99% of his trade aren't successful(getting profit). There are different types of trading strategy and you use the best strategy that would be able to give you more profit than your previous trading strategy.
But it is not exactly correct that day trading is not profitable. Just like you later in the post you said to use the best strategy and I think that is what is important to do. Look into the best strategy that you are consistently making profit then build upon it and continue taking your profit from the market. The market is always there and willing to give us profit if we do the normal thing but we are just humans , sometimes we fall but we need to rise always.
