Creative constraints help focus the mind. They also help avoid the problem of infinite choice when you are starting out. This is true for all creative pursuits, from writing and coding to painting, music, and cooking. A blank canvas can be overwhelming, so artists will sometimes use a technique called gridding to help them get started. I often use creative templates from masterbundles.com/templates/presentations/powerpo… to get the required inspiration. It has helped me very much.
