In my experience as a father of a 5 year old daughter there's nothing in life that more poignantly exemplifies the notion of things in life being both immensely beneficial and seriously detrimental than does having a kid. I have previously written about the downsides of having a kid before so I will just summarize some of them in bulletpoint:
-Tremendous drain on time
-Tremendous drain on resources
--Seriously, the time drain. I have to say it again because "holy fuck can I just have 5 min. alone?" is a common thought
-Being woken up at 6:20am with the lights being turned on, a kid jumping on you, being asked to play, etc
-In a span of 3 hours you might be asked 100 questions
-You have to play the same kids games over and over and fake enthusiasm each time
-You have to consider another person and physically take them with you whenever you plan to do anything
-Dealing with things like tantrums, crying, screaming, shit, piss, puke, injuries, spills (constant spills at certain ages), etc
-Just having to constantly be "on-" You're a teacher, a mentor, a guard, a babysitter, a cook, a cleaner etc all day long
Now, all that aside, all that shit you hear about parenting being the greatest, most rewarding endeavour in the world is (mostly) true. There are moments between her and I that are truly the happiest and most endearing of any in this life and I sincerely mean that. The feelings that your little one can engender within you are far and away better, more intense and more satisfying than any you can experience elsewhere. It always sounded ridiculous to me when I was younger but now I find myself experiencing it: I will sometimes think about her and I will feel myself starting to tear up (or feel like I am close to it). She is the greatest, sweetest, brightest thing in my life and I am completely dedicated to doing the best job I can so as to allow her to become a self actualized, competent, happy, free spirited, inquisitive, motivated human (and in all honesty, so far so good, but not solely because of me; she plays a huge role in it herself).
