I think it's a song about living life on the road. Without being bound by chains of dependency or having something expected of you. The line that best sums up the song is "Life of a drifter, that's the life for me". He's saying he doesn't need lots of money or fancy living to enjoy life and live it to its fullest, even his girlfriend(?) who calls him a liar or whatever will not hold him back. In a world of demands and prospects you're always expected to study hard and become a lawyer or whatever and have a materialistic life that isn't governed by you, it takes guts to stand up to that dogma and just hit the road; every new street corner is your new home and you are subject to none; without a master of your own.
