The instrumental song appears to consist of violin or another string instrument. It sounds, only in part, like "Mad World" but it is definitely not that song. This song appears to be pretty motivational, so I guess I'd classify it as "a motivational song"
The research I have put in thus far: I searched the entire comments section (via command + F) and I even posted a job on Freelancer.com to identify the song but with no avail. I think in order to identify the song, one must already know it.
If anyone could help, I'd greatly appreciate it.
Here's the link (it's the background music of the entirety of this youtube video): https://www.youtube.com/watch?v=wqEsTPaUZF0&list=WL&index=2&t=0s
