'The greatest gift you can give is investment in yourself,' says Sinead Kane on this week's Commit podcast and at the age of 17 she decided to be more pro-active and take control of her life. Being born with 95% blindness, growing up was about being left on the sidelines, but at 17, when a guidance counsellor said she shouldn't pursue law in college, that was when she decided to choose to be visionary, not blind. Incredibly, since she took up running six years ago at the age of 30, Sinead has completed the seven marathons on seven continents in seven days challenge, as well running in 12 hour and 24 hour races and holding the world record for distance run on a treadmill. 'Being optimistic is difficult and I struggle every day with it. The biggest bully in my life is myself,' she admits, but her success in life far outweighs any negative self-talk. We all make excuses for not succeeding and Sinead has more excuses than most, but her achievements are a reason for the rest of us to try and catch up.
