Basically this song is about stop trying so hard in life.. stop the competition nonsense. Oh I'm better than you.. so I'm gonna get all this. Indecision is basically like saying not being able to decide what is right or wrong or what your decisions are. "People keep on given advice", pretty much saying everyone keeps giving people advice, but in the end he doesn't really care about the advice. "Come a day when it won't matter, cause one day you'll be gone".. basically saying, stop worrying about everything going on and just worry about yourself for now because one day you'll eventually die.. saying life is too short to be worried about "big" things.
