Always ask questions

I noticed some people don't seem to ask questions in situations where they should be doing so. You should always ask more about the product you are buying. You could also ask others to know of a better way to do something. And when they do ask, they tend to ask the wrong ones. There are things that you should already know and there are those that you should ask the right person. Knowing what and who to ask are equally important.

One who asks a question is a fool for five minutes; one who does not ask a question remains a fool forever.

Some people refuse to ask questions to not look stupid. That is probably the worst thing they can ever do. Ask questions whenever you can.
