How to make “my posts” page

I think this is what you are looking for:

function my_posts_shortcode_wpse_135655() {
  if (!is_user_logged_in()) return;
  global $current_user;
  get_currentuserinfo();
  if (!empty($current_user->ID)) {
    $userp = new WP_Query(
      array(
        'post_author' => $current_user->ID,
      )
    );
    $content="";
    if ($userp->have_posts()) {
      while ($userp->have_posts()) {
        $userp->the_post();
        $content .= get_the_title();
      }
    } else {
      $content .= "You don't have any posts.";
    }
    wp_reset_postdata();
    return $content;
  }
}
add_shortcode('my_posts','my_posts_shortcode_wpse_135655');

Stepping through it:

1. Do nothing if the user is not logged in
2. Else retrieve the user data for the logged in user
3. If we have user data run query to get the user posts
4. Output the titles of those posts
5. Reset post data

To use this shortcode, just add [my_posts /] to any post or page.
