At some point in our lives, we all hear some version of "You can't do it." When that influential voice (whether outside or inside you) tells you why you can't--maybe that's the perfect reason why you can. At 27, actor, viral YouTuber, and one of the top former Vine stars Marcus Johns wants to shift our perspective on the resistance and obstacles that discourage our most powerful contributions.

Whether it's conducting outrageous experiments or creating content we love to share, some unusual people use the voices of doubt--including their own--as motivation to press on and prove them all wrong.

Sharing lighthearted insights from his life as a social media phenom, Marcus knows what it takes to be influential both online and off. How does one balance family, friends, faith, and fame--not to mention, finding the fun--and what does true success look like when the cameras are off?

With his signature wit and transparency, Marcus shares his unconventional thoughts on:

• How to overcome self-doubt and move ahead
• Knowing who's on your team--and who's not
• What it really means to follow your gut
• Developing your skills by embracing failure
• Remaining humble and sharing your success with others

A must-listen for any passionate go-getter, You Can't Do It may just be the magical phrase pointing you to the right track.
