What personal skills would you need to improve upon to be successful in your endeavors?

Interesting question: the first skill which comes to mind is the ability to make faster decisions. As a trained engineer I look for as much data as possible, turn it inside out, chart and model before coming to a decision. I’ve learned by experience the business world just doesn’t allow time for this type of behavior. I have to train myself to determine the importance of each decision, collect all the data possible in the shortest amount of time and then decide and move on.
Other personal skills include delegation of control. I can delegate but I find myself checking and following up on delegated activities more than I need to. I have to develop trust. This will come from surrounding me with competent people who I don’t have to worry about. In my job today I would with what I often term “B” players. People I don’t have control over and I must work with as a condition of my employment.
I feel I have the organizational skills and the selling and promotional skills needed in business.
