Managing time

So my greatest fear is coming to past, not being as regular as I planned to be on steemit. During the week days I'm busy with school and other projects, I get very tired to even make a post on steemit. I couldn't even complete my black and white challenge.
Gush! How can I manage my time and still give everything I do a very good shot?
Well, I'll try posting some of my literary works here.
Sorry for boring my followers with no post for some time
