Why did Cortes set sail for the Yucatan when he was afraid that the governor of Cuba might change his mind?

Cortes set sail for the Yucatan despite his fears about the governor of Cuba because he was driven by ambition and the potential for wealth and glory from the riches of the Aztec Empire. He believed that leaving quickly would allow him to secure his expedition before the governor could intervene or revoke his authority. Additionally, Cortes was motivated by the desire to establish himself as a prominent figure in the New World, which outweighed his concerns about losing support from the governor. Ultimately, his determination and strategic thinking propelled him to act decisively.
