I recently watched a documentary about Warren Buffett. It was a really insightful story that illustrated the key themes that underpin how Mr Buffett came to be the Oracle of Omaha. You don’t need to be a finance or investment professional to appreciate and understand these key principles on making good investment decisions. In fact, what I found incredibly useful was thinking about how three particularly Buffett-esque investment principles could have very clear and powerful application to how one should approach their career. Because put simply, you do need to invest in your career if you want it to grow. These foundations for investing highlighted by Warren Buffett provide a fairly good basic framework for how you should invest in yourself professionally to deliver value to yourself over the long term.
