Idea generation is infinite. You can come up with another one at any time.
Don’t hang on to an idea so hard that you fail to actually implement it. It may never be perfect, and that’s okay. The important part is that you try big, learn from the experience, and keep moving forward.
This is not the last great idea you’re going to get. Step out of your comfort zone and do something with it before you forget why it was so exciting.
