Hold On

Its basically saying don't give up. Regardless of what it is . “I've been grinding and grinding Oh, ocean have mercy

I've been grinding and grinding Oh, ocean have mercy I give you my life Oh, son of the sun

I've been rowing and rowing No sign of land so far in the flood I've been through fire and wind I'm hanging, feet in the depth

Drowning all day long in an ocean of stress Gotta find a safety raft, another wave is striking down”
