Sometimes it takes a bit to get back into the swing of things. In late december I had pneumonia and was hospitalized for like 8 days. Just that little bit has put a major damper on me getting motivated to put out videos. you just gotta put some time aside in your day, week, whatever to devote to working on your channel. Even if its just a few minutes a day to read forum post and research what direction you want to go with your next videos. It takes a bit but you'll work it out eventually. Just don't get frustrated. Instant fame on Youtube doesn't happen to everybody. For most of us it means putting in alot of work.
