Where Do New Ideas Come From?

I feel that new ideas come from our surroundings. Our surroundings influence us on the decisions we have to make. Ideas could come in a good way from surroundings or a bad way. For instance, if you get interested in biology or chemistry because you're family told you, then that is great. But, if you're friends tell you that you should start smoking, drinking and driving and taking drugs, well then you should really think about if you want to go with their ideas or not. I also think that a lot of posts  come from T.V. or books, a lot of ideas come from T.V. because people think that what they are seeing on television could be cool or exciting, when in reality what they have done is had the worst possible idea ever. I also very strongly believe that people should get ideas from the right people, or right sources. People should not fall into the trap of all these terrorists or people who will bribe you to do something wrong, because that is them giving you a horrid idea, and you fulfill their dreams...
