•Best shot - Don't put every video you shoot ,choose the best one according to you and delete the rest .
•Comparison-You should not compare yourself to the others youtuber ,you are unique in your own way . Eventually it will just detoriarate your confidence.
•Learn-Learn from others , other's videos ,TV Shows .Be curious about the techniques ask the question to yourself "How do they do it?" and research and improve.
