I decided at 30 to have kids. I wouldn’t say I wasted my life before kids, I just wasn’t ready yet. I still feel under prepared. I say that children is the hardest thing you will ever do, and I think that’s the source of downvotes I’m getting. I’m not saying that there are not other things in life that are hard. If you choose not to have kids, you can still have hard things in your life.
However, if you do choose to have kids, that will be the hardest thing you do. Emotionally and physically hard. You lose any sort of regenerative sleep for 5 years. Fitness routine? Bye bye. Energy? Out the window. Oh, you enjoyed the relationship with your spouse? HAH! And then you take the emotional stuff into it, like mourning the loss of the human baby you grew to love and falling in love with the toddler the baby became. And then the cycle repeats again and again until one day they don’t come back. It’s a 20 year relationship that ends with a partial breakup.
