I do not feel comfortable confirming more details of my personal experience of life, so I am going to continue hypothetically.Have you tried paying attention to what you are doing and believing the Lord for His help so you aren't clumsy?
Clumsy people are going to cause someone to get killed and/or cause destruction of property.
Also, although I understand that position as you are a business owner / manager, I ask where the line is to be drawn? Because, as you doubtless know, even "non-clumsy" people will inevitably make serious mistakes that could result in death and destruction to others! Obviously a clumsy person is more likely to do so, and that's your point, but still.
So what is God's solution to the clumsy man problem?
