How long does it take to get comfortable, proficient, and good at recording and mixing music?

We all come form different experience levels before diving into the world of audio recording. Some of us had experience with live sound. Some of us were musicians. Some of us were songwriters wanting to make better demos.

So how long did it take you guys before you felt comfortable doing the following:

Recording your voice or instrument on a computer?

Learning how to use your DAW?

Becoming fairly happy with how your recording sounded (though the perfectionist in us is never completely satisfied)?

Feeling comfortable enough to charge other people money for your services (if you chose to)?
