None !

You may say you have NO experience of work.  Fair enough.

But you DO have experience of living, of getting to be a teenager at least.

So, you've gone through many stages of growing up (though some are still to come).  Think what you've achieved so far.  Impossible to imagine when you were a baby, or a little child.  Just as it's impossible to know what it feels like to be elderly, or perhaps a parent or carer, or in your final years.  (But you probably will).

Approach learning this new skill in the same way.  You don't have to know what you don't know.  Just move one stage at a time.  I will guide you.  (It won't hurt).

And, as you've found before, doing it will create a pattern to follow.  So your body's sensations will help you, even if your mind doesn't feel like it'll cope :)
