Choosing your friends is also choosing your future weekends, habits and inside jokes.

A friendship is not only a feeling about a person, it is an agreement about how your time gets spent. Whoever you are around most sets the default activities, the standard humor, what counts as a normal amount of effort. None of that arrives as a decision. It arrives as a drift towards whatever the group already does.

Look at your calendar rather than your opinions and see who is in it. Then add one person who does something you want more of in your life. You do not have to subtract anyone to change the average.
