Hit the points. Working smart means achieving those kpi targets (both explicit and implicit ones) that truly matter, not “finishing ” all your work, which can’t be finished anyway .
What makes you proud of yourself? Why are you not doing more of it?
Are you learning, stretching, growing everyday at your workplace? If not, do something about it.
Dedicate yourself totally to something and make it great.
Check your ego. Restrain from the urge to talk and boast, seek to listen and really understand .
Being nice is good. More importantly establish yourself as a mature, firm professional who stands by his / her principles and values.
