In my younger years till now, most of what I learned were through experience and books read. When your reality is shaped by experience, there are a lot of biases developed in the process. One thing I am not comfortable with is talking to someone about things I went through or thoughts in my mind at present. When you get betrayed or let down by people you trusted or what you shared is used against you, one tends to clam up. Keeping thoughts, happiness, pain, depression, fear, mistakes, and joys to yourself. This is also the reason why I don't ask questions. It is not the lack of interest but to avoid the conversation from getting too personal.
It has made me stronger indeed. When I see young individuals with potential and going through troubled times, I reach out subtly just to let them know that they will be able to get through. Give advise if sought.
