I lost the will to live after the 2nd page, but as someone who has lived, worked and commuted from Bristol, London, Swindon, Birmingham, and Leeds, I can assure you that long distance commuting absolutely is NOT viable in the medium to long term. It's expensive and over time, just wipes you out physically, mentally, and emotionally. Having a stressful or demanding job bookended by a mega commute isn't worth it.
Unless you have some sort of Mickey Mouse job that just happens to pay megabucks and you don't care about having any life outside of work, a daily commute from the Isle of Wight to London is the most stupid thing you can possibly do. As that's not even taking into account trying to do it a £1k banger.
