You can't just sell your product/service. You have to connect with the individual, hear them out, have those meaningful conversations, and address all concerns. You can't be pushy and have to hit each step of the cycle in order to be successful and avoid any hiccups later down the road. 

Attitude is everything. Maintaining a positive attitude will set the tone for your customer/student. You must "sell" or "promote" yourself and your energy before you can successfully sell a product or a service. 

I didn't realize how much mirroring or matching body language, speed, tone, etc. can have an impact. As I reflect on some of my interactions with coworkers, I can pinpoint who I have better rapport with just based on our conversations and body language. It's really quite interesting and says a lot!

Really think about your communication before proceeding- the method of communication, your message, the tone, and what you want to accomplish. Be more mindful and strategic with it.
