Life Is Short (2016)
Having kids is hard, but yeah it is one of the best things.My wife would get annoyed when we would pass someone walking and they would see our kids and say "enjoy your time with them while they are young!"  Because she hadn't slept and was stressed out.  She would think "you enjoy your freedom and your full night of sleep!""The days are long but the years are short" is a quote I think about a lot.I think the key is the same whether you have kids or not: peace of mind in the present moment.  If you are happy now you won't regret it later.
