Don’t be afraid to go for it and try something new. If it doesn't work out, it wasn’t meant for you. Move on and try something else, and bring along the new skills and resources you've gained during this process. Repeat.
Do you second-guess your ideas and find it hard to confidently present your work? Try talking confidently, with passion and excitement. This will help to generate confidence, and make the creative process much more fun for both you and your client.
Role models inspire you to be better. But when you compare yourself to them, it can mess with your confidence. Remember, they were once at the level you're at now, and your journey is unique. So focus on improving your craft, and soon you’ll be up there too.
