I think doing a secobd job in today's world would be much more difficult. You should be either younger or devote your life to your family, forgetting yourself.
In this case, I think HIVE can be a second job opportunity if one will be patient and consistent here.
There is so much part-time work available that is unskilled and relatively mindless, that throwing a few hours here and there shouldn't be too hard for most. But, it isn't glamorous.
