Hold it together.
Often the difference between those who lead and those who follow is merely this.
In life there will be instances when things would not go your way. We all operate on assumptions and it should come as no surprise that some of those assumptions turn out to be wrong. The more fundamental the assumption, the harder the hit. When this happens, you often feel like everything is falling apart.
As an entrepreneurs you are probably going to go through this feeling one too many times. It never stops.
Great leaders hold it together when confronted with their world falling apart. Not only do they hold it together, they analyse the situation properly and make the right decision.
This quality singularly differentiates leaders from followers. Not IQ, not ability, not skill; just being able to hold it together and doing the right thing.
