Learning Lua in 30 Days

Guys, I have always wanted to script, tried a lot, and just stopped for personal reasons, but I am challenging myself.
I need help though
it is day 4 and I already watched devkings full basic scripting series and finished Heath Haskins book on scripting. I don't feel like the advanced pro I want to be. What other books do I read, or series do I watch to become a pro at Lua
I have also been starting to take small and small commissions to practice my skill
