I enjoy helping people through analogies, so here it goes-

Finding an idea is not that hard. What is hard is when you put on binoculars and search everywhere for ideas. You keep looking and looking but nothing seems to make sense. Here is your solution- Stop looking through those binoculars and look what is in front of you. Be observant of everything that you do during the day. Every thought, word, and action. Listen to people and yourself. Don't say "I need to find an idea" say "Hmm, every problem that I encounter today has a solution. Let's see how I can tackle these problems."
