We are all important in one way or another. Being a celebrity does not make us more so or not being one less so.
What makes us important is using the skills and knowledge we have in a way that helps us and others. If we can help just one person in our lives, we are important.
Just recently I was told by one former client that I helped him immensely during a difficult time for him. I never knew and it made me feel tremendous. And someone I do not know wrote to say he was following me on LinkedIn and was patterning his career after mine. Wow.
We never know who we will impact. We may never know. But we keep trying and do the best we can. and that is what makes us important.
