On the road to becoming a best-selling rapper, there are bound to be a few bumps -- not to mention a few detractors -- but what if your own family doesn't support you?

Then you keep on pushing, just like B.o.B did.

On the latest episode of MTV's "This Is How I Made It," which premieres Saturday at noon, Bobby Ray -- who landed at #1 on the charts with his major-label debut, [article id="1638472"]B.o.B Presents: The Adventures of Bobby Ray,[/article] in 2010 -- reveals that his father was not too thrilled about his career choice.

"My dad will tell you that he wasn't too fond of me when I first started rapping," the Atlanta native explained. "My dad was a preacher. When your dad is a preacher ... the things you wanna say as an MC, they don't really go hand in hand.

"I remember I was walking through the house with a rap book, a do-rag on and some headphones or something, and my dad stopped me," he said, recalling one pivotal moment. "He was like, 'Why are you trying to be something that you're not?' "

As you can imagine, young Bobby Ray didn't react well to his dad's comment. "I was appalled," he admitted. "I was like, 'What do you mean, something I'm not?' I'm an MC, I' m a lyricist, I'm a rapper -- I love this. If someone tells me I [can't] do something, I'm going in the exact opposite direction."

Although the journey was difficult without having his dad in his corner, B.o.B said that it pushed him to work even harder. "I think if I would've went through life and there would've been nobody hating on me, and there would've been nobody writing 'you're wack' in my rap book, if I didn't get booed at the talent show, I don't think I'd be here. I wouldn't have wanted it badly enough."

"This Is How I Made It" airs Saturdays at noon ET on MTV.
