Do you think telling people about your life can interfere in how you progress?

Do you guys think telling other people about your life can interfere in your progress and the goals you plan to achieve in life? I don't have the habit to go out there talking about all of my plans to strangers, but every time I'm talking to a woman I tell her about my plans about my life and how I plan to achieve it. I mean it is normal to do it but usually it's not someone I really trust to tell everything because Im just getting to know the person, but I cant keep my mouth shut these times because I want her to know me better, even if its not a girl I plan dating or something
