I've noticed that before people take you seriously and give a listening ear to what you have to say, you need to present yourself as someone who can be valuable. It just like someone pitching you to buy something that you don't see its value, no matter how good a sale man or woman this person is, you'll feel very reluctant to purchase whatever it is the person is pitching. It's the same thing with us humans, when people listen to you speak the first two times, they've made up their minds about you. In their minds they could be like, "this guy is spitting value, he's spitting wisdom" depending on what you say. No matter where you are mind what you say and how you say it because there are people there that'll analyze you based on what you say and how you say it. Always present yourself as someone with value in either your respective fields/profession or in life generally. When you do this, you'll find out that people will take you more seriously than they did before.
