At some point of time, trying may lead us to a more adventurous path. If I were to choose, I see a ray of difference, I would give it a try. Who's know actually we can change the "outcome-we-thought-it-will-be". But definitely not when you started trying and you know the outcome remains unchanged and you still go on trying.
Trying not as in you have to start something straight. You can start by going out. If you judge a person with just the first look, how would you really know the person. (But not applying to people you have know long ago).
Maybe that's the differences between horoscope thinking. I will choose to take up the adventurous side while cancerians choose to go by safest road.
Actually, if you did not think of trying would you have consider the outcome?
