How is it I'm still at 300 Sale, after 4 years!!!!?

I need help here, looool
I’ve bean an exclusive author at Videohive for 4 years now, I admit that I wasn’t so active in the field, but I gave what I could (btw I’m a student of medical sciences) and I admit that some of my early template wasn’t “GREAT”… but I wonder how new authors are coming to Videohive with few templates and getting a lot of sales, I’m so happy for them really, but it made me think that maybe I’m missing on something???

Any creative ideas my fellow creatives???
