What is your yêu thích song that's motivational, like about overcoming obstacles in life and is upbeat?

I know this is a ngẫu nhiên question, but for a conference that I'm going to in a few weeks, we need to do a video and a song within the video has to be a song that goes with the conference's theme, which is "Scaling New Heights." If anyone has any suggestions as for a band/song,etc. that would help me, I would greatly appreciate it! =D
