As the saying goes, " There is no harm in trying". I will then add that, " rather, there is harm in not trying. People are always scared or afraid of taking risk and so they will rather give excuses of not trying or find a way of avoiding something. Until you try something, you might not know the goodness of it. Even if it came with a 'bad', you would have learnt something in your life for the next challenge ahead. Rather than not trying it all, it would be better to try and fail. After all failure itself is a learning process. Why don't you try that thing you have been shying away from now.
