Once that happens, you will not be who you are as of right now. You will see it, its completely different world.
I myself thought I won't be able to handle kids at all, and at same time I do want to have kids. One DAMN woman that proves me that I was dead wrong about raising kids and she really really hit my face harder than I could ever image. Im not sure how to make a damn long story short, and that was in Oregon, that woman who was orally deaf, learn sign language when we met online as friend. Her hubby divorced left her with two kids. She said she only want little help with discipline her kids when I was with her. I thought of the discipline method, and I didn't realize it backfired and I couldn't understand her and tried to ask her to tell me what she is talking about. I decided its not worth trying to be friend with her anymore and left and met my wife shortly afterwards and ended up having two kids of my own. That is when I changed who I was, who I am right now. I wish I could thank her and respect her that she was damn right after all. I have not heard or speak with her ever since before my first boy was born.
Having your own kids can change you, I hope you can be a great parent.
