Slam Dunc S2E35 - For too long I've struggled to say no to people

For too long I have struggled to say no to people for fear of letting them down - I hate the thought of people thinking I'm not giving of myself or I am selfish. However I have found myself reluctantly saying yes only to regret it.  Do you ever wonder is there a better way to work? Or to find time in your life for the things that really matter?
