There is no such thing as owning a business without interruption. There are growth struggles, leadership concerns, and tough decisions that must be made on a daily basis. Sometimes the wrong choice is made and consequences must be suffered.
Similarly, very few businesses will start and finish with nothing but failures in between. Success is what business owners strive for and should be championed.
The point is that businesses will go through many successes and failures throughout their existence, and perhaps the most important thing that I have learned as a small business owner dating back to 2005 -- a business I created after performing an internship at a reputable company -- is that neither failures nor successes should be dwelled upon if you wish to be as productive as possible in growing your business.
It was at that internship in 2005, at a sports agency in Atlanta, Georgia, that I learned this important lesson, that I now call "The Two Minute Drill." It was something taught to me by the owner of the company, who had experienced a lot of success in various business ventures throughout his lifetime, and credited this advice as being a key component to his success.
The Two Minute Drill essentially boils down to this: When something very good occurs in your professional life, be it the landing of a new client or delivering as efficiently as possible on a task, take a total of 2 minutes to celebrate it. Drop everything else and give yourself a pat on the back, boast a little bit and maybe even yell aloud with joy. After those 2 minutes, get back to work, because there are many other battles to conquer.
Similarly, if something bad happens, such as losing an important client or finding out that you lost a big potential investor who could have fueled your company with the capital it so desperately needed, don't ignore it. But don't ruminate on it. Take that same 2 minutes you would have spent celebrating victory and get the anger out of your system. After 2 minutes, get back to work, as you don't want that anger to negatively affect your other tasks and potential victories.
I've heard others provide similar advice. There's no right amount of time to spend celebrating successes or upset in defeat, but you absolutely don't want to take too much out of your time to do either. For me, The Two Minute Drill works like a charm. The challenge is putting it to work. Give it a try and see how it works for you.
