    Life experiences can show one's "grit"（坚韧）． Complex challenges early in life helped the following people develop skills that got them to the top of their professions．

Ursula Burns， Chairwoman， VEON； Former CEO， Xerox

Howard Schultz， Executive Chairman， Starbucks

Schultz grew up in public housing in Brooklyn， surrounded by poverty， and was the first in his family to go to college （on a football scholarship）． After training in sales， he set up the company that would later buy Starbucks． "In the course of the year I spent trying to raise money， I spoke to 242 people， and 217 of them said no．" he said．

Geisha Williams， CEO， PG&E

Her parents fled Cuba when Williams was 5． By 7， she was her parents' main translator in talks with lawyers and accountants at grocery stores they owned in New Jersey． The experience did help her． "I went from thinking I could be a manager to thinking I could do something much bigger．" she told Fortune．
