We are all creative.
Sometimes we forget how to connect with our source of creativity, but that's something we can always find again.
First, get some rest.
Then, get messy, get untidy, get away from your usual routine.
Be a child. What was your favorite thing to do as a child? Draw? Colour? Ride bikes outside? Do those things again - awaken the child within you!
Remember, the more you flex your creative muscle, the stronger it becomes.
Don't be discouraged - most of all, don't compare your spark to anyone else's. Find your spark, accept it, embrace it and get to know it more.
