Depends on the person, their circumstances, their goals in life and other factors.
For me, driving is the best option at this point in my life. If I was 22, had a degree, knew my abilities could get me far in life, had ambition and no family to support, I would consider management.....only after going FT driving. It is possible to work your way up the ladder and the resume bolstering experience would help in securing management jobs at many other corporations. The down fall is, once you leave management at UPS, a lot of managerial workers bounce from corp to corp. Another reason I would not do it. Compounded by my age, my family and lack of desire to start working my way up a ladder at this point in my life and it doesn't make sense for ME.
