Your calling does not need applause to remain valid.

What you are meant to do does not become more real when people clap or less real when they do not. Validation is pleasant and occasionally useful as feedback, but treating it as the confirmation means your direction is being set by whoever happens to be watching.

Do the work through a stretch when nobody notices, deliberately, and see whether you still want to. That answer tells you more than any amount of applause. Then find a small number of people whose opinion you actually trust, and stop counting the rest.
