I understand this part.
Why? It becomes boring as time goes by.
Even if you are making profits, you start to wonder if that is it. Are you stuck with that routine?
This is also the reason why I don't do it every day. I felt it before and I am still feeling it now just 1 hour looking at the movements in one exchange.

I really envy those who can still continue up until now. That means they really love what they are doing.
