There are some things you need to let go of to live happily

The neighbor's grass is not always greener and the person you're with may have a trade-off you can not see. Your neighbor may have a bigger and better home and car, but his family life may be a mess. Artists in your online community may seem to sell like hotcakes, but in fact he might make things he hates.
Other people have no right to decide whether we deserve happiness in life, and you are entitled and have to really love yourself. You are a whole person and everyone deserves happiness. So you know, that you also deserve it.
You do not have to worry about molding to fit what people expect. In fact, you can actually find more people who fit you. With the rise of the Internet, this is easier than ever.
