One thing I learned, is you probably should not come across as someone who says "no" a lot to their manager - if you like working where you do in general. Ask open and positive questions, like "that could be a good idea, where do you think we can use it?" (or find even a better phrasing for this, managers are often very defensive, especially when they are not very skilled) rather than "how do you think that would work?" which is often my first response... hah!
