Sometimes all it takes is someone to notice a small thing that you are doing well and let you know it matters to bring a smile to your face.
I think we all (as humans) seek approval in different ways and want to be validated. A lot of times we only hear when we do something wrong or make a mistake... this can be pretty defeating.
It takes a little effort to notice something positive about those around us and little bit more to point it out.
What would happen if we all started doing that consistently?
