Being bored isn’t proof you’re doing it wrong. A lot of getting really good feels boring from the inside.

Getting good involves long stretches where nothing seems to be happening, because repetition is how skill gets built and repetition is dull from the inside. Excitement is a poor measure of progress, since it mostly tracks novelty. If you quit every time interest drops you will collect beginnings and never own anything. The flat middle is where most of the actual learning sits.

Separate the question of whether this is boring from whether it is working. Judge by your record of the last month rather than by mood. If it is working, stay, and make the boredom easier rather than treating it as a verdict.
