Craig Ferguson has worked his way up through the ranks in Hollywood from having a recurring role on The Drew Carey Show to hosting his own late-night show. As he tells ET, he has a rather simplistic approach to his career and towards his late-night show that has kept him successful.

The Scottish native told ET that when it comes time for his late-night show, he simply takes it step-by-step. "I put on a suit," Ferguson said when discussing his late-night preparations. "I'm telling you--that's what I do. I put on a suit, and there you go. We'll see how it goes."

That same simple-yet-effective approach that has granted him success on The Late Late Show with Craig Ferguson has been a longstanding philosophy for Mr. Ferguson. "I tend to think [of] life as short chunks," he revealed. "I try and keep it in short amounts of time 'cause if [I] start thinking about, 'What [do] I want to be doing when I'm 50 or 70?' I go crazy."

Ferguson, who will turn 50 this week on Thursday, stated that he never really gets too far ahead of himself and half-jokingly said that it feels as though reality hasn't set in and that his success could be terminated at any given moment.

His day-by-day approach also led him back to visit his native Scotland, where he filmed a week's worth of shows that will air this week. Ferguson brought along his celebrity friends Mila Kunis, Michael Clark Duncan, Rashida Jones, and a few others.
