Sometimes it's easy to get wrapped in school, grades and marks from external sources. It may seem like the end of the world when all your hard work and effort gets reduced to a number on a page, especially when you think that you're worth so much more.
Be sure to take a deep breath and remember that everything you do is appreciated not only by those in the collective around you, but also by yourself. Look inwards and see the inherent worth in the thing you have created and don't be afraid to share it with the world.
Appreciate and share the work of others around you and be sure to relish in it, creating doesn't have to be a competition even though we seem to be taught otherwise.
