Lyric discussion by mentalism 

Cover art for Keep Your Head Up lyrics by Ben Howard

Could it be about cheating on a partner? The first two verses seem to suggest this.

Notably: "And I cut my mind on second best, Oh the scars that come with the greenness. And I gave my eyes to the boredom"

Song Meaning

i dont think it's about him cheating with someone else, it's more him cheating with himself. "cut my mind on second best" meaning he put himself as second best in the relationship and now he wants to put himself first if you get me
