Well online marketing have two phases
one is when you have just started, here
you are puzzeled and will give lot of time
on it. I too have given 14-16hrs in my
early days.
In the second phase it's easy, this is when
you have setteled, most of your work is
automated and in fine motion. At present
I don't give more than 4-5 hrs daily. Sometime
I am even away for a week or so. I am able to
give quility time to my family and friends.

Just remember you have to settele down
then you will have lot of time.
