Be honest /sci/, is there any hope of actually making it in an intellectual pursuit when you've squandered your youth on stupid shit and spent countless hours on activities such as 4chan, pointless youtube videos, porn and videogames?

I'm 24 and I'm starting to think no matter how hard I try i'm simply too far behind to get to the level of the kids who actually developed good habits and studied from a young age. I've stopped most of these harmful activities and significantly cut back on the remaining few in recent years but i still feel like my brain is damaged. I feel like I can't think as well as the others in so many different ways that would be too long to articulate efficiently here.
