How do you evaluate success in a business 2,how can you work with a difficult boss,3.how do you handle stress at work?

Business Success should focus on Customer satisfaction(both internal and external), Profitability and Business continuity(sustainable share in the competition environment).

Difficult bosses shape your cutting edges - look at ways and means of dealing with such bosses, understanding their personality and emotional make up could be the start of better working relationships.

Stress will always be there to keep you soaring - learn to prioritize and stick to the plan unless other more important issues crop up on the way and you really have to attend to them. Use the Big rocks and the 4 Quadrant among other models for prioritization. Let passion take your steering wheel, that way stress remains at management levels. Keep a smile even when it is not possible

I agree with the answer, Mr. Wesley Kasanzu
