Hi folks.
I am self-employed as a Musician in Manchester UK, and I don't drive.
Most of my work involves playing Highland Pipes at Funerals, Weddings, Parties etc. I travel by public transport and cover most of the North and Midlands. It means getting up pretty early some times as most of my work is during the day and I might have to get to a Funeral 100 miles away for 10:00am.
I don't see it as a disadvantage (except occasionally when I could have done two or even three bookings on one day) the reward is comfortable relatively hassle free travel and an opportunity to see the seasons change from trains that very soon leave Manchester and enter some great countryside.
I once worked out how much a car would cost to run and maintain not to mention learning to drive and buying one, and what I spend now on travel would be about the same.
So all in all I'll stick with public transport until I get so rich I can afford a personal Helicopter.

All the best PP
