Growth sometimes means choosing the same boring right thing for the hundredth time.

Improvement is usually imagined as a series of new decisions, when it is mostly one decision made repeatedly long after it stopped being interesting. The hundredth time produces the same result as the first and feels like nothing, because novelty and progress are not the same system. Getting bored is a sign you have reached the part that works.

Notice where you keep switching methods because the current one went dull rather than because it failed. Stay with one for a full stretch. The boredom is the cost of the thing actually accumulating.
