Thus the benefit from making mistakes is overblown because Sun Tzu advises us to avoid making mistakes if we can help it because let's face it: your objective is success, not errors. Learn by planning and anticipating problems, not by fixing problems that could have been prevented. Having said that, however, mistakes will happen and one must get back up quickly from a setback and continue working. If there is one thing that never fails it is persistence.
What is persistence? It is the relentless pursuit of your goal. Success? Keep going. Setback? Keep going. Two left feet? Keep going. Nighttime? Keep going. Weekend? Keep going. Others stopped? Keep going.
You don't need talent. You don't even need advantages. You only need the will to continue the mission when everyone has given up because it is just too hard and difficult. You know you're in this zone when you've forgotten to eat. You know you're in this zone when the only time you must stop is you keep dozing off due to a lack of sleep. Yet your mission is the first thing you think about and the last thing you remember each and every day.
If you're not in this zone, then find an activity you can believe in to get you there. If you think this is unrealistic, then you don't truly understand how short life really is. Don't be in the position of looking back and wishing things could be different. You're here now. You have this chance again. What are you going to do this time around? Please don't say to make a mistake. Not when you can get to work and hit it out of the ballpark, leaving nothing and nobody in doubt.
