Question

what can be a thesis statement for an autobiography about your-self

Answer 1

Your thesis statement must include <u>factual information</u><b> plus your position/opinion/stance. Without your position on the topic, it isn't a true thesis statement.</b> So think of this sentence as the angle you want to take on the topic and what you intend to prove by the end of your paper. (If your statement is simply factual, then there's nothing to prove!)

This is one of the very best places I've seen online to help students write good thesis statements. It shows you sentences that aren't thesis statements and how to turn each one into real thesis statements.

What is it you want to emphasize about yourself?
