Being successful in business does not happen overnight. At times, it might even challenge your character as a person. A degree in business can help you be successful, but in the real world, not everyone is. As for me, the utmost quality you should have is perseverance.
There is a lot to risk in doing business. It is your time, effort, and money. There will be moments you will fail, but it is how you get up, and pushing forward until you achieved that success you wanted. A quick thinking in decision making and diverting from Plan A to Plan B or C can save what you started.
As what the Bible says, with patience comes perseverance that produces character and gives us hope.
