Happy Friday the 13th, everyone. Have you had any bad luck yet today?
Superstition ain't the way - unless it works for you. If you need a four-leaf clover and black-cat-filtered glasses to believe you can jump that little bit higher, or run that little bit faster, or lift that little bit heavier, I say go for it.
Believing you can is half the battle. There's a spectrum of attitudes from an "I could never do that", "I can't do that", "I can do that", to "I will do that" (and ultimately "I've done that"). Some simple things will happen whether or not you think they can. Maybe you don't think you can get the wire of your headphones to tangle - but if yours are anything like mine, they will tangle all by themselves! Other things will require a conscious, sustained effort. If you can't believe that what you're doing will ever work, how, other than by being crazy, could you continue working in that direction over months, years, or decades?
