I think the biggest was self-confidence. I never really felt like I knew what I was doing, that I was winging it. I’ve always been out on my own and teaching myself how to improve my work - it can be incredibly rewarding but sometimes can take a lot of motivation. The growth of YouTube and what you can learn on there has been fundamental to evolving my skills!
The pandemic was also a huge challenge. I went freelance full time in August 2019,  but in March 2020 I lost all my work. I’d just picked up some of my first major freelance production projects and it all disappeared overnight. That was very tough, and the summer months were pretty scary/quiet.
Eventually, it all came back, it taught me to be more comfortable with having downtime and made me more comfortable with not having loads of work on. I think when you turn your passion into your job it’s common to get validation from how busy you are and that can be dangerous when you go through quiet periods.
The pandemic has also helped me prioritize projects I want to work on and also encouraged me to dedicate more time to volunteer my skills for charity work.
