I particularly like what I am reading:

"In a fast-moving, competitive world, being able to learn new skills is one of the keys to success. It's not enough to be smart — you need to always be getting smarter," says Heidi Grant Halvorson, author of HBR's 'Single Nine Things Successful People Do Differently'.

"We need to constantly look for opportunities to stretch ourselves in ways that may not always feel comfortable at first. Continual improvement is necessary to get ahead," says Joseph Weintraub, coauthor of the book, The Coaching Manager: Developing Top Talent in Business.
