The first type, if it is a piece of pure music that makes you excited and full of energy and wants to fight for your dreams, you can find string music with a cheerful rhythm, such as "Croatian Rhapsody", "Croatian Rhapsody No. 2", Maxim's "Exodus" is a more classic or more modern one. I have been very impressed by Josh Vietti's violin music in the past two days. I recommend starting with "Black & Yellow".

The second one, and the one I think is most likely, is that when you hear that piece of pure music, it evokes your past memories, which in turn inspires your passion for your dream.
