How many times have you met somebody that claims to be an expert in their field, but hasn't actually done any personal development for months or even years? Is it even possible to be an expert in something if all of the things that you have learned were years ago? How many tradespeople do you know that go on courses to get better at what they do, after they have finished the College course/diploma they finished when they were a teenager? No matter what your chosen line of business is, you can take simple steps to build your expertise, and so build your credibility as a thought leader in your sector!
