"Acting" is a skill cultivated over time. When I first started working, I was a person of strong character. Put nicely, it meant I had personality and spoke my mind; put bluntly, it meant I lacked tact and didn't always know when to hold my tongue. So when I was a newbie in the workplace, my boss seemed like someone with little skill but a big temper. I resented every task he assigned me.Once, when he assigned me to sweep the streets on behalf of the department, I impulsively snapped, "Why do the good jobs never come my way?" After several job changes, I learned to "put on a show." Regardless of my inner feelings, I'd do the task first and think about it later. Gradually, I found enjoyment in it. From a certain perspective, "putting on a show" is actually a form of professionalism.Everyone experiences moments of weariness, doubt, confusion, or even anger toward certain people or situations. But if you frequently let your true feelings show, you're the one who ends up at a disadvantage. Of course, "putting on a front" must be done in moderation. If you end up bottling everything up until it makes you sick, or if your act alienates colleagues and bosses alike, then it's better to just be yourself.
