No, you can not. Everybody has his personal limits; limits in talent, limits in intelligence, limits in endurance and perseverence, limits in initiative, limits in social skills, limits of personality style, limits in stress-tolerance, limits in judgement-making, etc, etc.
When people push against their limits, it is admirable. When they go past them, it is usually sadly obvious because, without great luck, defeat and failure are almost certain. Life and reality are stern schoolmasters.
I am a believer in rigorously honest self-appraisal as well as a "seaching, fearless moral inventory." These things are narcissistically injuring - but liberating. Furthermore, they can help us steer our ship and avoid the rocks.
