Wrong Thinking Help please. To you?

If you decide your career by looking at someone's career. Because you like that career, you also want to make it a career. should I give credit to this person? Because you didn't know about that career before meeting that person. But when you come to know that person is in a xyz career.. So you also thought of choosing that career. Because this career is of your interest. should I give credit to this person? I guess I shouldn't give him credit because meeting that person is a coincidence. Because when I start studying for that career, I get a very severe headache and I feel nervous in my heart. I feel that person has made a huge contribution to my life. Is that really his contribution according to you? Or is all this just my illusion please help me
