Don’t take action to prove them anything – You simply recognize their possible negative reaction and follow up with what you were planning to do.
You don’t do it for them, you do it for yourself.
For instance, if you arrive at a social event and you notice a few people staring at you or judging you, make it your point to connect with as many women/people as you can, being super friendly and approachable.
The key is to not let these people’s doubts or judgements stop you ever!
makes sense right?
