Beneath Roger Federer's never-ending charm is a fierce, warrior-like competitor that the tennis world has never seen the likes of. Federer's brilliance was on display again on Sunday. He routed Marin Cilic in straight sets 6-3, 6-1, 6-4 to capture his record setting eighth men's Wimbledon singles championship.

His most recent career milestone at Wimbledon and 19th major victory came after many people had written him off just a few months before.

OK, he's too nice to have haters. However, after a lengthy six-month layoff from the tour last year and a five-year drought on majors, he did start to develop quite a few non-believers over the past few years.

Many of them have been vocal about it, including John McEnroe. In fact, earlier this year Fred Segal wrote an article outing those experts that publicly stated that Federer would never win another major.

Federer's Brilliant Advice in Five Words

"I kept believing and dreaming," Federer said in his post-match interview after his record setting performance. "If you keep believing you can go really far in life."

Why is this advice so brilliant? It seems so simple, right? Well, the fact is that many people give up on their dreams. They suffer a few defeats and things get hard. Then they quit and accept a mediocre version of themselves. They make compromises on their dreams. They stop growing, learning, and working on themselves.

It took Federer five long years of hard work to win another Wimbledon. In order to achieve your dreams, you have to keep believing in yourself. It becomes harder and harder after years of losing and coming up short.

But if you can persevere through the hard times, continue to work hard, and keep believing in yourself, anything is truly possible.

Roger Federer proved that yet again by winning his record-setting eighth Wimbledon and becoming the third-oldest male to win a major.

Now, the question everyone is asking is, "Will he regain the No. 1 ranking atop the ATP Tour?" Well, you certainly won't catch me on record saying he won't!
