We all need a break on what we are doing because we can be "burned out", we can lose our self because all we care is about our work or trading career. If we cannot manage to exercise everyday, at least talking to other people that does not relate to crypto or going out of town is also a good thing to do to refresh. This also helps to become more productive. I remembered the motto of my previous company "Work Life Balance" so yes everything should be balanced.
Honestly I hear that people have those, and I do advice people to have a break here and there, but I never really felt that. I work 7 days a week, so I work every single day, I do sometimes have some other work that I just have to handle so I work less sometimes, I agree that not my every single day is hard work, sometimes I have to go out for either a good reason like out to eat or out with friends (none so far this past year because of pandemic, this is old times) or something like that.
However I never felt burned out, I have literally taken my laptop to a vacation, a daily vacation, while my friends had fun, I just sat back and wrote and worked because I wanted to, I never gave up, I do not remember last time I didn't work for a whole day, and been doing this for years. I understand some people do have that kind of burn out phases but it really never happened to me.
