Emile Ledure tries to answer the question, “how do you build products that stick and last in a healthy way?” I really like his approach in Healthy Retention: What Makes People Keep Coming Back? I especially appreciate the principle “Have fewer but better interactions”:

You don’t necessarily build retention by pushing people to use your product every day, you do it by bringing high value every time they need it — even if it means being absent most of the time. So don’t be greedy. […]

Fewer but more memorable experiences help you build stronger and deeper relationships with your users, which creates loyalty in the long run.
