If you've been following The Joy Within for a while, you've probably heard me talk about resonance - your natural, inner energy. But, you might not be clear on what, exactly, this resonance is - or, frankly - why you should care about it.   So, today I want to talk about why resonance matters. I'll give a brief introduction to it, and then we'll go deep into why it is so fundamentally important, because I think being able to tune-in to this feeling is the single, most important skill you can develop.
