We have surprisingly short memories. Unless you offend or say something completely stupid, the words you use to introduce yourself will be forgotten.
In fact, sometimes it’s even good to offend. ;)
At networking events, some people paralyze thinking about the perfect way to introduce themselves and end up missing a lot of interesting meetings and business opportunities.
The first words are not that important. I try to make mine as un-remarkable as possible:
Hi, I’m Etienne. What brings you here?
It’s the last words that people will remember. You can’t plan discussions. Act and learn to improvise.
