About 8-10 hours everyday
Too many, on school days I guess it should be somewere between 4 & 5 hours, in weekends it's usually around 10 & 13 hours per day... Which is TOO much for a teenager but heck, it's what I love so...
Too many as well, I hope it pays back someday.
It's 4 to 5 hours a day for my various activities, including NB.
Weekends can be from 16-18 hours in a day and workdays about 8-10 hours. Owning your own business is a lot of work!
