"I've put a lot of thought into my life, decisions I've made in the past," said Roethlisberger, who in April was suspended for six regular season games by Commissioner Roger Goodell for violating the league's personal conduct policy.
"I've been working closely with the commissioner on ways to make changes, corrections," Roethlisberger told reporters in his first comments since the suspension.
Roethlisberger, who returned to practice on Tuesday, will be allowed to take part in the Steelers' final offseason drills and to attend training camp, which begins July 30.
