Yes! I was a C student. I had it drummed into me that wasn't good enough. It took me many years to realise I am good enough and to work past all that negative re-enforcement that was thrown at me every day for several years. Now I have a great job, a lovely wife and two beautiful children. I live in a lovely house in west London. I am financially independent and I love going to work every morning. If that isn't "good enough" then god knows what is!
