There is a word play in German: „Selbstständig bedeutet selbst und ständig.“ - Self-employed means yourself, continuously.

Some people do that but it is more of a choice than you might expect. For most of the twenty six years I was doing it I rarely worked more than three or four hours a day.

I know it as 'Being self employed is great, you control your own time and can choose any 80 hours/week to work"

Be self-employed and be your own boss!

Ooops, now you have multiple bosses (each client).
