You won’t dream in a new language after one week of an app streak. You’ll dream in it after a year of not quitting.

A week of anything gets you familiarity; a year of it gets you fluency, and the two feel similar early enough to fool you. The change you want happens below the level you can see, in the part of your head that stops translating and just knows. There is no version of that which arrives in seven days.

Move your goal from a streak to a season. Ask what you want to be true next June, then set a daily amount so small you will still do it on your worst day. Boring and unbroken beats intense and abandoned.
