Is it true that many people study psychology in university level originally for self-help reasons? Is it true that many people study psychology in university level originally for self-help reasons? I have heard about this and I wanted to ask what are people's opinion about it. Someone told me that it's very common that psychologist's first motives for the field started from self-help and later shifted towards helping others, research, etc.
Even psychologists joke that we study what worries us. (I am one). 

And that doesn't pass as we go through the ranks.  Our interest might move on though.

What does happen is that we are firmly told that speculating about 'cases', ours or anyone elses, is not what psychology is about.

Psychology is the -ology (study of) psyche (Greek word).  Psychologists are rigorously trained in research methods.  We are expected to be able to frame inquiries, conduct inquiries and evaluate inquiries.

As we go into the profession, we will learn other skills as well but we never leave that insistence on thinking methodically about the question we are asking and sticking to evidence.

Hope that helps!
