Missed opportunities in love..

So everyday we see, walk past, meet and talk to people that we’re attacked too but yet we do nothing about it.. why do we do it?! If you see something you want, you buy it! If you want to eat something specific then you eat it.. so why is it that when it comes to choosing or picking a partner to spend the rest of our lives with we don’t grab the opportunity to say “Hi, I think your really good looking, would it be too much to ask for your number?” Or to even go up and talk to this person..Most believe that everything happens for a reason and they weren’t meant for you reasons such and such but what if they were but we never gave them the change because we never had the courage to choose what we want! What’s everyone else’s experiences because I can’t help but think that I’m just awkward and ill never have the courage to do anything about it...
