Im 33 years old and 5 months ago at a friend's party i heard a voice in my head saying "you have to learn how to play the guitar"... I indeed was on drugs, but very lightly actually

So i borrowed the guitar of a friend. Its an old piece of crap he bought 10€ 10 years ago but its ok enough to me. I started admiring guitar players on youtube like Sungha Yung or Igor Presnyakov, and of course Neil who has definitly the best teaching skills. I unfortunatly dont have 300€ for the TARGET program but i did buy the lesson "Is there anybody out there" to get me started. I dont like strumming for now, i like to pick my strings. I have 2 questions if you dont mind :
- can you point me to songs like "Is there anybody out there" ? Its an easy and beautiful one, and i'd like to practice more of the kind.
- I bought a thumbnail pick out of curiosity and i wonder if its a good thing to start learning the guitar with it or not ... it feels really uncomfortable

thanks for reading so far

have fun!
