Your hands learn faster than your confidence does. Keep going until your confidence catches up.

Skill and the feeling of skill run on different clocks. Your hands pick things up quietly through repetition, while the part of you that judges your work lags behind and keeps reporting the old number. That lag is why people quit at the exact point they are starting to get good, and why old work often looks better than you remember.

Find something you made three months ago and look at it next to something from this week. Let the comparison be your evidence instead of your mood. On the days you feel useless, treat that feeling as out of date and do the practice anyway.
