I agree with all the pros that you listed. While I am new to this forum I am in no way new to trading and I have seen the great 2017 and thought once that trading is all gain. Come May 2018 I realized there is so much more to trading. Trading style, TA and hodling whether  by choice or not 
What I am trying to say though is that day trading is my best opt most of the time but this require passion and time devotion.
