#4: Date Different
This suggestion goes hand-in-hand with possibly trying a lunch date. If your schedule is swamped, then you have to change some things. You have to find a way to do something different.
To begin, you need to start taking risk and doing things outside of your comfort zone. That cute person on the train you made eye contact with on the way to work, you should go introduce yourself … Say hello and see if there is any connection.
Or you can take things to the next level and even try a speed dating event. A speed dating event can have you meeting ten to twenty other singles in an hour or two. This is the equivalent of going on a month or two of first dates.
Even if speed dating may not be your thing, get out of your confront zone and find new ways to meet people that fits with your swamped schedule.
