Jessica’s Answer:

Yesterday’s comment becomes today’s question…

“Realistic” is going to be different for each individual and each networking situation. 
If you are an outgoing individual who is attending a large function with 500 people, the potential is very high. If you are a shy individual, your goal is to meet the number that pushes you out of your comfort zone while being productive.

A networking opportunity can occur at an intimate dinner for 6, a movie screening, or a seminar (to name just a few).  

I suggest you set a number goal that is:

1. More than you would normally reach out to
2. In line with the number of people who will be at the event
3. Do-able; set yourself up for success

Remember it’s not about the number, it’s about creating relationships with people and getting out of your comfort zone.

If you have a question, put it in the comment section.
To your success!
