Because I work online, I don't set a time for how many hours I have to work, I will work if I'm interested, and I'll rest if I feel tired or bored, and I'll come back when I feel refreshed and excited again. I try to keep my free time productive, if I get bored on the RIF forum I will switch to the Mylot forum, or other applications so it doesn't get monotonous and I don't get bored quickly.
