Ideas have value. Most good ideas are a result of the unique perspective of the person who has them. Many years of life experience (working in an industry, talking to others, etc) usually go into coming up with a new idea, not to mention research and detailed thought about specific problems.

Ideas are very common, every person has them. But good ideas are rare. Consistently coming up with good ideas is difficult, and it might be worth it to give some thought to the process.
