If you walk out to your car one morning and have a flat tire, you’re not going to go and slash the other 3 tires because 1 is flat. You’re going to fix the flat and get moving. If you have a “bad” day, it’s not the end of the world and it’s definitely not a reason to throw in the towel. Just get back on track and live lean. And yes, we ALL have flat tire days. Even the world’s most elite athletes have flat tire days – they just fix it and move on.
