It's the apostrophe that makes all the difference

Recently I was speaking to a triathlete during a training session and they said "I can't...." We've all been there but if we say we can't then it's true and the more we say it the more we affirm it in our minds.  However if we skip the apostrophe (and miss out the t) then we can.  Having a can do approach increases the chances from 100% certain that you won't to a high probability you will. 
We all have strengths and weaknesses and I struggle with kick drills at swimming - basically I suck at it.  So although I dislike the drills I give it 100% as I know it will only get better if I think I can rather than think I can't.
So for the next month pause before you say you can't and switch the emphasis to you can and watch the difference.  Just remember can't lives in won't street!  Have fun, I know you can!
