Find Someone You Can Bring Half Baked Ideas To
Following up from the previous post about talking to people who intimidate you, you should also have some people that you feel very comfortable bringing unpolished thoughts to.
This should be someone patient, with a talent for discussion. You should be able to bring them ideas and talk about them in a way that helps you test and evolve your thought. This person should be able to come at ideas from a different approach that you might and be honest with you but still make you feel comfortable.
This can be helpful when you have a bold idea that seems like it might have merit but you need some help solidifying and validating it's core ideas. This process can be similar to "rubber ducking" but with a more active duck.
