Jill Biden, wife of US Vice President Joe Biden, today said the world is a tough place for women but insisted that education is the key to success. Biden, an educator for over two decades, visited a girl's school - Anjuman-I-Islam - in Mumbai this morning.

School girls welcomed Jill, who was accompanied by her daughter Ashley, by playing the band. Thereafter, the US second lady briefly toured the school and met the girls studying in tenth standard, interacted with them, motivated them to study hard and wished them luck.

"The world is a tough place for women everywhere including work place. It feels good to see young girls getting educated. Education is a powerful weapon, it helps in some or the other way," said Jill. "Everyone wants to pursue their dreams and do better in life. I think all this is possible because of education. I love teaching young women," she said.
