"The biggest risk is not taking any
risk... In a world that’s changing really quickly, the only strategy that is
guaranteed to fail is not taking risks." - Mark Zuckerberg
You miss all the chances that you don’t take. In order to make a change and achieve your goals you have to be willing to take risks. Staying still is not part of progress, it won’t help with your objectives and is the surest way to fail.
Taking a risk doesn’t mean you’ll succeed, but it will get you closer than simply not trying.
You already have a no for an answer, so why not take a risk to achieve your goals?
