you're thinking metaphorically again :P
[Reach for the stars
And your dreams will come true
I could be a coward
but only to you]
This part all refers to the same thing, but none of it is metaphorical to the answer. It is what it is basically.
[I may not be strong
but my talent I gain]
this part refers to how you get the answer.
[I say who I am
but thats not what you need
The answer is there]
You know who I is, but that is only relevant to a certain part.
[but on time do not heed] time is not important :) but when I say time, I don't mean game time, it's not available anytime in the game, but it is not a forced time limit.
