We are told many things. Use your inside voice. Check yourself. Be brief and concise. Use your filter. Chin up. Suck it up. Shut up and get the job done. Minimize. Keep it clean and neat. Behave. Tame it. Tone it down.
Indeed there is a time and place for all that.
Whatever way you handle it, please make sure you are keeping the best parts of you. There is also a time and place to give it a stage, a microphone, and a spotlight, to let megawatt you shine.
