I wouldn't call this fear. It is more of an insecurity. You seem to lack confidence in yourself. Hence you think that others will gain more from you than you gaining from your hard work. Think of this as knowledge. The more you share, the better you become yourself. Same with doing x. The more you do, the better you get at it even if it helps others. In fact, if it helps others, even better for you. Most people are not looking to "gain" anything from you or take advantage of you. Also look at the alternative. If you never do anything because you think someone else will benefit more, you will never do anything for yourself. You are the loser at the end because that imaginary person who MAY benefit more probably does not even exist. I would say most likely they don't exist.
