How to show posts based on author.

How can I can show posts that only the author made based on who is logged in. but the administrator can see all posts?

Here is what i have at the moment

<?php
$args = array(
	'posts_per_page' => 100,
	'post_type' => 'ticket'
);
query_posts($args);
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>

bla
bla
bla

<?php endwhile; else : ?>
			<tr><td colspan="6"><?php _e('No tickets found.', 'woothemes'); ?></td></tr>
		<?php endif; ?>
