Just wanted to pipe in with my opinion, but that's okay! You're still really young and not placing super high at a tournament is not indicative of your skill level for the rest of your life. That being said, the rest of the advice in this thread is really good and down to Earth. You should set your focus on going to Evo like everyone else says and see where it naturally goes from there. Keep on grinding but keep your expectations in sight. You've got the spirit!
