What are bad recommendations you hear in your profession or area of expertise? The worst recommendation is to keep your ideas and data secret until you have a paper describing these results accepted in a journal. Anytime I have a crazy idea or see an unexpected result, I talk about it with my colleagues to see if they have seen anything similar and whether they think my idea is crazy. This is the fun of science. Multiple scientists with different experiences and expertise can collaborate and get to the right answer much faster than a single scientist.
