In your pursuits in life, you may become Everyone’s somebody, but can never become Everyone’s everybody. Why not, then, go for becoming Someone’s Everybody.
This works in career, academics, relationships and life in general. As far as work is concerned, one doesn’t need to be an expert on everything, but certainly being the best in some focused areas in life helps! This will give you more respect in the long run and happiness & satisfaction all along the way.
