You can, you should, and if you’re brave enough to start, you will.
Making big mistakes is the occasional byproduct of making big strides. Big mistakes can only occur when you’ve planned and thought things through. If your carefully laid plan turns out to be a mistake, it may cost you. But it will also give you exactly the information you need to modify your strategy or change your course. You learn, you adjust, and you come back with a stronger, more impactful strategy that works. In the long run, big mistakes are the best feedback we ever get. The most successful people in life are those who make the best use of their mistakes.
