[header] How to behave professionally [title] Arrive five minutes early each day. [step] Don't be that employee who's barely making it in the door at 8:00am or the one who regularly comes fifteen minutes late. Get up early in the mornings so you can arrive to work early; this will show that you are dedicated to your job. 
[substeps] Don't rush out at 5pm, either. Stay a few minutes afterwards to check emails or finish up tasks.
