If you have a brilliant idea - great! But it is just one percent of what you need to become an inventor. Thousands of people have good ideas every day, and just a very few of them turn into inventions. Of course, not every idea that comes to your head is worthy to become an invention. But if you think your idea is useful and workable, you should consider developing it further. If your invention idea can be turned into a product, you can hope to earn some decent sum of money with that. However, in order to become a successful inventor, you'll have to work hard.
Don't give up! The good news is that you do not have to do everything yourself. If, for example, for creating a prototype of your invention, you do not know how to create a computer model you would like to use, ask a specialist to do that. If your InventHelp Prototype prototype requires some wooden or metal parts and you are not a DIY guy, order those parts.
