I would say that motivation and drive to learn and get better every single day is the most important skill you can have.
I would say that Laracasts is probably your best resource for Laravel which helped me to find a job and help colleagues. Oh and it's an amazing feeling when I can mention watching Laracasts videos on my LinkedIn profile as experience and colleagues at my first company say stuff like "Are you Ruffles from the Laracasts forums?!" :D Thanks @JeffreyWay
I learn mostly from video tutorials so I am subscribed to some other popular web development video tutorial platforms besides Laracasts.
I've also bought a few useful PHP / Laravel courses which I've learned a lot from (haven't touched Adam Wathan's book Refactoring to Collections and his course Test Driven Laravel yet).
I also watch conference talks to get some tips and tricks, help people on these forums here from time to time and I have a few books that I want to read but I have not found any free time to focus on them. Newsletters are piling up in my email and I read some of them.
Before I forget, I also learn a lot from working on real projects where I have to implement different features for clients. It taught me how to figure out stuff on the spot, by reading docs, googling and asking people on forums or the Larachat slack channel.
Maybe the Awesome Laravel list will help you find some resources.
Attending Laracon is not a bad idea, if you have the money and time to attend it. Laracon Online will be interesting.
I don't see much value in certificates really, because the technology is moving so fast and they might be useless after a while. Adopting a new technology quickly is more important than a certificate if you ask me.
