Did Theodore Roosevelt Say “Believe You Can and You’re Halfway There”?

“Believe you can and you’re halfway there.”
Documented wording
“The credit belongs to the man who is actually in the arena …”
Context
Why the attribution sounds plausible
The saying fits Roosevelt’s reputation for action and courage, which helps explain the durable attribution. An authentic comparison appears in his 1910 “Citizenship in a Republic” address: “The credit belongs to the man who is actually in the arena …” Compatibility with his ideas, however, does not establish authorship of the popular sentence.
Attribution note
Credit the popular sentence to “Anonymous” or “Popular saying, often attributed to Theodore Roosevelt; no verified primary source located.” Use the 1910 Sorbonne speech when a documented Roosevelt quotation is required.
