When I as in the 4th grade my teacher, Mrs. Hawkins, told me something that I never forgot. She told me something that has influenced my life and many decisions I have made throughout the years.
While helping me prepare for an oral report about Francis Scott Key, she suggested that I sing the Star Spangled Banner in front of the class. The idea of making such a spectacle of myself in front of my entire class frightened me out of my little mind, so I said simply, "I can't". She frowned and barked, "Can't?! Can't is for the weak minded. Can't never did anything". Powerful stuff. Thank you Mrs. Hawkins.
Mrs. Hawkins was right, you should never say that you can't do something.
To this day I think of Mrs. Hawkins, those words, and the valuable lesson she taught me whenever I am confronted with difficult situations or am asked to perform difficult tasks. I never say that I can't do something.
Instead I say - "No way you crazy bitch", "I don't want to", "No thank you", or "I am far too busy".
