 I continue to invest in myself, especially in the public speaking skills. In the past, I took all possible classes about public speaking skills. I believe I spent over $8,000 or $10,000 in learning public speaking skills. And that actually payback significantly. Besides the public speaking skills, I also invest $60,000 in learning all possible different kinds of skills, such as leadership skills, management skills, negotiation skills, how to influence with authorities, communication skills, all possible skills, and I believe that all power skills for us to master to advance ourselves. I made a very strategic decision earlier in my career that I need to learn how to lead and how to manage people before I even become a manager.
