If you don't have a real job it becomes a great activity but if you have another job it will be difficult for you to divide your time. That's in my opinion.
Who said it would be difficult to divide time if a person had two jobs that he had to complete every day? I personally always work in two different things, the first is real work and the second is work in forums, but I can always divide my time on each of my work and even have more time so I can spend it on my family too, this all depends on someone in managing his time, except for the lazy people, it is clear that he will always waste his time so that he is unable to share it.
