Skill lowers the emotional temperature of difficult work.

A large portion of the stress in difficult work comes from not knowing whether you can do it. Skill removes that specific uncertainty, so the work remains hard but stops being frightening. The emotional load and the technical load are separate, and only one of them is reduced by practice.

When something feels unbearable, check whether the problem is the difficulty or the doubt. If it is the doubt, the answer is preparation rather than resolve.
