so anon, i recommend the following way of breaking your shyness. it does work. spend about a week just working on a very simple thing: when you're going about your day, make it a point to look in the eyes and smile. that's it. eye contact and smile. try and keep that up for a week. then the second week, as you're walking down the street, simply try dropping a random "hi" as you walk by.  over time, you will eventually have a convo pop-up. don't worry if you fail, just know you're doing better than most.
