I totally agree with you on this. There are parasitic friends and there are bad influencers friends also and it's important we understand our personality and goals in life while making friends.

Those friends that are just after what they gain from me and don't add value in my life not even motivational words, I drop them with wisdom, my circle of friends matters a lot to me and am "in" in searching for those quality friends that I can work together with to achieve success in life.
