I never said they should "give it a try" I simply said, don't be so quick to jump to no if you are unsure.I was talking about people on the fence, not those already saying no.
I would argue that something is lost, the experience. I will always encourage someone to try something, or to at least weigh all the options instead of just saying no. No is easy, yes is hard but often times leads to something much greater.
Have you been 100% certain of every decision you have ever made in life? Have you never done something that may not turn out right, but you did it anyway? Obviously having a child is not like jumping out of a plane. It is a life long commitment vs a 5 min adventure with the slight possibility of death. The premise is the same though. If you are weighing your options, don't just jump to no out of fear of the possibilities. You could possibly be missing out on the greatest adventure of your life.
Like you said, if you don't have them you won't know what you are missing. Just like if you don't jump. Me personally, I'd rather jump.
