A creative block is an impasse in your creative process. It is when you want to create, but feel stuck, stagnant, and at a loss for what to do next. (The most well-known creative block is Writter’s Block. I use Creative Block because it less medium specific.)
Here’s the thing about creative blocks: your block is like playing with a strong willed three year old. You want to play a certain game, play with a certain toy, or play in a certain way, but she won’t join you. You really just want her to do things your way, but she will have none of it.
