The biggest problem with finding a “business idea” is when you call it an “idea”. Calling something an idea implies coming up with something truly novel, which is extremely difficult. The trick is to shift your mindset and start searching for “problems”.
Businesses aim to solve problems. When you think about it this way, it’s much easier. All you have to do is find a problem. In your own life, in someone else’s life, doesn’t matter. Unless your life is perfect, there should be plenty of problems all around you.
Dropbox as a business idea would sound something like “Cloud storage for your files”, but Dropbox as a problem would be more like “I’m sick and tired of emailing files around”.
Businesses are solutions. You can’t come up with a solution until you know what problem you’re solving. The good news is, problems are everywhere. Happy hunting.
