LONDON, United Kingdom — Our weekly motivation contains curated career advice from leading executives, entrepreneurs and creatives in conversation with BoF. Today's mantra comes from Tadashi Yanai, the founder and president of Fast Retailing, parent company of Uniqlo, Helmut Lang, Theory and Comptoir des Cotonniers (see his BoF500 profile here):

You have to be positive and believe you will find success next time.

This week, we are pleased to introduce three new partners to BoF Careers:
