How could people distinguish which chance is a temptation for the worse or really a clue for a better chance??

Say for example, you are facing a diverged road, and yet you don't know which one you should take... And say, to make it worse, you have been followed by the angel who always guides you and the devil who always tempts you....

Now, how would you distinguish the chance and the temptation???

I have this kind of offer, which I find it realistic, promising, and bright. But the thing is, I don't know that this is a chance or a temptation from the devil??? Is this a temptation or a sign that this is the road I should take?

What decision should I make???
