Should We Sacrifice Personal Relationships for Gains?

This is a question that led me to the end of a lot of personal relationships and I think it is especially relevant for people who want to keep being themselves but also do not want to isolate themselves with the outside world (like me). I have came to a clear conclusion to this topic and I think it is worth sharing.

The key, or base principle that we are following is that we are keeping our friend connections and relationships minimal. We do not want useless people in our lives--because that would not only make our lives complicated, it will also reduce our focus on what we prioritize in life. I believe that we should only befriend people whom we think are playing a major role in the growth of ourselves, as at the end of the day, (or at least I think), life is about us and how we balance everything that happens. We are the center of our own lives, and we should always know that. Even if that means sacrificing everything else for our own eternal gains, that is worth doing because that would mean we are actually benefitting what really matters in our lives.

This may seem selfish, and I am aware of that. But it is only when we clear out everything that is irrelevant to us, that we are able to find true meaning in what we do and believe in. Thus, in conclusion, are personal relationships worth sacrificing? To me, yes--as long as we know that it is for the good of ourselves and we will benefit from this decision in the long-term, then we should do it without thinking too much.
