Hi! No problem :3
Motivation becomes a problem if learning is difficult in the beginner stage or when you reach an intermediate plateau, so dont worry! Try to find something you enjoy and then do it in Japanese, whether it be watching music videos, tv, or reading. Motivation for me is what I can use the language for in the future (for me it would be a job). You can get motivation if you find a penpal who speaks the language and you want to communicate with them. Try writing a diary on websites like italki.com or lang-8.com, that could help too. Good luck!
