Reluctance is the phase of the first contact.
You are used to do things using methodology/tool A. It works, you can get things done. One day, you stumble upon methodology/tool B. What is it? Ah, it claims to replace and improve A. Mmh. You know B since 5 minutes (and A so well) that it seems a simple, different way of approaching the same problem. It is not attracting you in any way; B is close to disgusting you.
Interest is when after months you stumble on B once again. What was it? Ah yes, the stuff that wants to replace A. Why didn’t you get more into B? You don’t remember. (There is no real reason for it.) Where did you encounter it? YouTube; Reddit; your grandmother; an online forum; colleagues; friends; your great aunt who you meet twice per year. You feel like someone is already using B with a degree of success.
You start watching YouTube videos, reading articles and blog posts, asking people. After a bunch of days you realize that you don’t want to waste more time on B. After all A gets things done to a degree that satisfies you. You abandon B.
Trial is the beginning of the end. A regular Tuesday morning you decide to set aside an hour to learn B with the goal of replacing A in the long term. Before this moment, you had other, sparse, contacts with B, but the cocktail of motivation, free time and boredom of this special day gave you the last push.
In around 40 minutes you are done. Surprised, a feeling of pride and uselessness pervades your body. You are happy.
Adoption is the pursuit of the same feeling that you felt the first time you used B. The upcoming days, the upcoming weeks B takes over more and more up until when A is entirely forgotten. You have adopted B.
