In general, I am hoping the design will breathe a sense of peace, creativity, and lightheartedness. I tend to enjoy artwork as a general rule, or simple drawings that even children could make (say with a simple pencil line).
The person looking at the image should be able to feel the sense of "relief" coming from the "release of creative ideas" from the mind.
I like the idea of a silhouette of a person's head "releasing birds", as if those birds were thoughts. (It represents "liberating the mind)." However, I am concerned that the final product might look too "cliché", so this is just an idea about how the design could illustrate the title and subtitle.
The image of birds of 7 different colors could also work.
Hoping the words "7 mental blocks" and "creating your own life" will pop out, somehow... and maybe also the word release to reflect the movement in a different font style? And maybe also "Creative Powers". But I have no definite idea about what should stand out more in the title.
I like the idea of a light enough water color in the background (like a canvas) from which several warmer colors could pop out from, or maybe a dominantly blue (aqua-like) background / cover.
The cover is for a standard size PDF document.
