They care by solving problems.
They care by being there when the team needs them.
They care by being honest, authentic and candid.
They care by making things simpler and smoother for themselves and those around them.
They care by striving to avoid office politics and back stabbing.
They care by being the team mate we all wish we had and strive to be.
They care making our common working space a place we are all eager to come to in the morning.
And I would pick a reliable, self-aware, well-rounded, face tattooed, green haired and barefoot colleague that's comfortable in their own skin any day, over any well-dressed, high maintenance, drama king / queen.
What's interesting though, is that even knowing, and thinking that, I couldn't help but be spontaneously biased towards he or she who made the so-called effort of dressing to look the part. And that's a problem.
Also, I am nowhere near being that ideal team mate. More like a work in progress >.<'
