Personally I realized day trading is so hard already, it requires staring at your computer all day and being too conscious of closing positions. I personally do not enjoy it, I prefer going long on a trade and exit when comfortable. Combining day job with active trading is not feasible for me at the moment
As long as you are capable of earning money in the trade, better keep going. It happens at time when your initial cost of investment is low. However if it was not low, better decide what to do by looking at your profit margin.
