How do you learn to work past doubt? We spoke to Christna Sass, the co-founder and president of Andela. Prior to co-founding Andela, she directed the Program department of the Clinton Global Initiative and advised the President and CEO of The MasterCard Foundation, a $9 billion global foundation working to advance education and financial inclusion for youth in Africa.

Yes, Christina has experienced failure and fear but she has learned how to move past that to build an amazing career that helps people around the world.
