When people don’t see you coming, you get to prepare without an audience.

Attention changes what you can do. Being watched means every attempt is a performance, every mistake is public, and the pressure to look competent competes with the work of becoming competent. Going unnoticed removes that tax. You get to be bad at something in private for as long as it takes.

If nobody is paying attention to you yet, use the window rather than resenting it. Pick the skill you would be embarrassed to practise in front of people and practise it now, badly, on your own time. The visible version can come later.
