title: Git checkout to recent commit
body: <p>I have a total of 24 commits, and I had checkout to commit 15. How can I go back to my last commit?</p>
  <p>Note: I have run a lot of commits. For instances,</p>
  <pre><code>git revert, git checkout, git reset.
  </code></pre>
  <p>I don't know my last commit name, id, or even the files. All I know that I have committed, but I am not there.</p>
  <p>but I could not go back to my latest commits.</p>
  <p>Thank you</p>
