when you ARE a child, your sensations are very pure and simple. you love, you like or dislike, you fear, you get happy or mad or sad ....
I want to talk about fears. when you fear from something, you probably have a source of fear, outside, and a target for the fear, which is probably, yourself. it may be you life, your health, your success, your joy etc.
But it's definitely INSIDE you.
as you grow older, you obtain the confidence to overcome fears you have, you get capable of controlling your position in some cases, stay fit to some changes and keep balance.
But there is a thing which changes everything! having a newborn!
a baby would probably been the most amazing experience of your life; but this is serious and real, it will bring a huge responsibility with itself.
what I noticed most, in my own case, was the cycle of same fears I had for myself, but this time with a target much weaker than me, OUTSIDE of me and out of my control.
same sources, different targets...
I do not recommend anyone to marry or have children or not to have one. these sort of things are subjected to considered personally, but be aware of such responsibility before you have one.
having a child is not an obligation, but being responsible for his/her life is.
