What I found interesting about these small talk conversations is that they can be very deep and meaningful if you are being honest. Most of the time I have a lot going on in life and on my mind. When I get to briefly talk about my frustrations and my ways of approaching them, I noticed that my opponents could resonate and be encouraged by the discovery of the fact that they are not alone in different human struggles of life. By being honest in admitting our struggles, emotions, questions, before others even in a quick conversation can serve as an uplifting experience for both sides, giving you something to relate to and connect to in another person in a wider perspective of a community.
When you feel comfortable, don't be afraid to share joys and hardships, and the ways you learn from them or get stuck on finding answers.
