"whether you think you can or you can't, you're right."
This is such a stupid saying to me. I get what they are trying to say and they are trying to be motivational, but if you think about it philosophically, it doesn't make any sense.
What if a person has a split personality? Or a split opinion?
Does that mean half of you can and the other half can't?
What if some days you think you can and another day you think you can't?
What if you have a hormonal/blood sugar imbalance that affects the way you think on an hourly basis?
Or adult ADHD? Then what?
I could go on.
