I am awful at grading, hopefully one day I can get better but I guess its just practice. Did you jump straight into it and learn on the job?
I worked as a Frontend Web Dev for a small agency (which I still work for) but due to poor projects that are mainly WP based I lost interest. Slowly picked up filming and now work as an editor/cam crew. Learning as much as I can is exciting and just love absorbing new information. Who knows, 5 years down the line I might be somewhere else but I think I am on the right track. Luckily I was chucked in the deep end (recently did a commercial as B cam for L'Occitane, edited by me) so had to learn on the job, something that many videographers struggle with initially.
