Making many decisions in your role as a Leader will inevitably lead to making some wrong decisions.
Don’t be afraid of failure, of making the wrong decision. Failure in a business environment is widely regarded as part of being a Leader as long as you stand by your decision and learn from the mistake.
Whatever you do, don’t try to hide your failure, or try to blame someone else for your decision. Accept failure, try to understand how your decision led to it and make sure next time you consider the reasons for your earlier failure when making a decision. Just don’t postpone your next decision because you failed last time.
