1) Don’t dismiss someone so quickly or be afraid to give them a chance!
2) Get used to being out of your comfort zone. Put yourself out there in the world, and start interacting with more people, without any pressure or expectations.
Don’t make your first impression too quickly or set it in stone. On a first date, many people come off as uptight, shut-off or over-confident when they’re feeling nervous. Give them another chance to shine!
