What do I do?

Security is something that I desire.
But not necessarily in regards to finance.
It's just that I require to know
Exactly which way to go.
If your light never turns yellow,
How will I know to slow?

I do not know if what I'm doing is right.
I just want whatever will leave you happy at night.
Tell me to leave,
And I'll try not to put up a fight.
But say something.
Tell me what you want me to do.
