What did Johnny 3 Tears mean when he said, "To hold all we know and let go with both hands"?

Hollywood Undead saved my life, so I've been looking for a single lyric to get tattooed over my self harm scars as sort of a tribute for them saving me. Johnny Three Tears' verses have been the deepest to me, so I picked out "To hold all we know and let go with both hands" as a good one. I take it as letting go of what we know completely, not hesitantly, and to not dwell. I was wondering what other people see it as.
