Full time trading won't be boring if there is profit. When we make some prediction, and if the same won't happen in the real time market it won't be profiting. When one completely depends on trading for life needs, and we don't get the required amount surely it'll be disturbing us. So, when we don't find success in trading it is good to have alternate means for living.
You always have options in life if you are no longer succeeding and you feel that you are not happy then go on and proceed to your life, find things that will allow you enjoy while gaining profits. There are lots of different views and opinions since there are people who are enjoying day trading and keep on getting successful positions.
