I'm not the best at giving advice, but I can tell you my strategies. I also feel like I'm not that much of a comedic person, but I do create comedy sketches. I have the hardest time at times finding out what my next video will be about. I usually get my ideas from other videos and then tweak them into my own original sketches. It's kind of hard for me to explain but I'm sure once you get that video idea, you'll get the ball rolling on how to make your particular videos unique from others. Also, making parodies out of a new trend or a new viral vine or video could also help you with easy video ideas. I'm sure you'll find something that works and will be successful at it.
