Regardless of which category you fall under, your best and most creative ideas will always require a lot of digging. You will have to get rid of the initial creative ideas you uncover so as to access the ones lying beneath them. And the strange thing about ideas is that they don't die, you can't kill them. The only way to get rid of them is to use them up in something else. As you keep using up the ideas you have, you uncover more ideas. And soon, like me, you will have your head full of ideas.
The most special thing about digging up ideas is that you'll begin to uncover uncommon ideas, like rare jewels, and you'll also become an expert at valuing ideas. You will recognize all forms of ideas and their value, whether they are your idea or someone else's. You will be able to do more with each idea you have and become a big picture person.
Finally, I'll advise that you try out all your ideas. Except you've surrounded yourself with bad influences and have evil ideas, in which case you should change your environment first to have noble ideas. Then everyday do the most you can towards implementing your ideas. It's a very fulfilling way to live. And it's what I do. Everyday I sleep very happy knowing I have put in my best at giving wings to my ideas. I wake up the next day with vigor and the desire to continue from where I stopped the previous day. It makes me feel unlimited and rich in resources (mostly intangible resources).
