The practice session nobody sees still gets counted by your future.

Unwitnessed work does not feel like it counts, because nothing acknowledges it at the time. The ledger it goes into is not a social one. It is what your hands can do without thinking and what your mind reaches for without effort, and that accumulates whether anyone claps or not. Recognition and accumulation run on separate clocks.

Do the session you were about to skip because there is nobody to tell about it. Keep a simple count somewhere private. The point is not proof for anyone else, only that you know what you have put in.
