Garbage in, garbage out. It’s one of my guiding principles. I think the precursor to that, or the catalyst to that is the mindset. if you are coming in with a mindset to fail then you’re going to fail and the above holds true. However, if you come in with a mindset to win or to succeed, then the results will be different. Inherently, our perception and mindset affect the results and how we perform.
Past behaviour and results are good predictors for the future.
