Below are things to consider when meeting new people and interacting with people you see everyday, all while being yourself.
1: Look at the person in the eye when you meet them
2: Smile and listen with intent
3: Repeat the persons name when you meet them and when you are concluding the conversation
4: When you walk past them, try to remember their name and use it when you greet them - that will stand out to the person and make them feel remembered, which will in return make them remember you.
5: Positive attitude is always remembered and goes a long way.
There is a book I read that helped my communication skills and in a way helped me have memorable conversations.
I hope that you find it useful: How to Talk to Anyone, by, Leil Lowndes (also available on Audible)
