Life is only easier if you have lived a worse life. You don't miss what you've never had.
Some people are glass half full and others half empty and I'm pretty sure it's just how your wired up. I never wanted for anything growing up and my parents were great to me and my siblings, I know people who have had an awful upbringing and yet they still plod on happily in life after shit that would probably have tipped me over the edge.
