Whiplash (2014)
If you didn't seen this film. That is the first thing you should do. Both main characters young Miles Teller and J.K. Simmons played the role of their lifes.
Short description:
A promising young drummer enrolls at a cut-throat music conservatory where his dreams of greatness are mentored by an instructor who will stop at nothing to realize a student's potential.
Yeah it doesn't sound interesting on first, that's what I thought but you will change your mind 100%.
When film had came to the end I was under the impression for few hours and after that I was motivated to do sooooo many things., nothing ever motivated me so much.
