I am not and I am failed to do it. A successful day trader will commonly need extra time and energy to work. If we have been working fulltime outside and then also focus on the daily trader regularly, it will really make us exhausted. Although the result may be promising because we can earn so much money, but, we will really lose energy, time, mind, an also focus. But,t his will also depend on different people. What kind of person you are? If you can really manage your time very well, no need to have long hours to be back home after work, and the full-time job is not kind of job that really stressful and tiring, you may be able to do also day trading. And it may happen if this is not kind of full-time day trading, but only daily trading to earn money.
For me, I am focusing on my job and als long term holding. This si less risk and also not really exhatisng for me.
