One thing that I have noticed about this world is that a lot of people do not like to see other people happy. It's a shame really. I don't know what causes people to despise other people's happiness- perhaps jealousy, a lack of self-worth, etc., but regardless of what it is, it should really just stop. Whether it be ignoring someone when they talk about something they love, telling someone to stop rambling on about something they are enthusiastic about, or even worse, doing something as an attempt to prevent someones happiness, it all hurts.
One of the saddest things to me is when someone is going on about something that is important to them and then in the middle of the conversation, they simply stop talking and say something along the lines of, "I'm sorry, you probably don't care about this," or, "Am I boring you?" At some point in time someone must have made them feel like the thing that they find so important doesn't matter, and now when speaking of it they err on the side of caution. I know, I've been in this position and felt this way multiple times. But, just because some people show disdain towards what makes you happy does not mean that your enthusiasm needs to dwindle in the slightest. Actually, it can be all the more reason to be enthusiastic. Show those people what it's like to feel passionately about something, because obviously they're lacking that sort of greatness in their lives. Let this remind you that having something that brings you so much joy, is not something that everyone gets to experience, so really be thankful and feel lucky that you have found something like that.
So, to all of you people who have attempted to kill my enthusiasm at some point or another, you have failed, and my only hope for you is that one day you find something that floods you with euphoria, because it truly is a great feeling.
