Slow texting after some time = normal behaviour.
You can arrive at this conclusion after some proper testing.
By proper, I mean (key 1:) how you approach your problem + what you test exactly + how different your tests are between each other.
Key 2: small changes to underperforming methods = still underperforming. What does this mean?
Key 3: your source = part of your approach = should be tested (think: at a bar in person vs. at a chess club in person vs. on a dating app over text)
Key 4: offer is most important. Can be nicest guy, but what you offer = suck = no one will care. (think: best car sales man selling you broken car)
Last key 5: you won’t know anything unless you track it.
Carry this with you everywhere in life.
Thinking, Fast and Slow: Your System 1 (primitive) will react, jump to conclusions, and overwhelm your System 2 (logic).
Slow it down with the scientific framework above.
Good luck
