anon my dad died when i was 17, I was fortunate enough to learn a lot from him but every day I encounter something that makes me wish more than anything I could pick his brain or ask for advice.
He always tried to instill the value of hard work, and dedicating yourself to being the best at whatever task you undertake, and like a teenage shitbag I resisted a bit, and of course like so many men since the dawn of time, I now realize he was right.
But you don't have to try and turn the tanker ship that is your life around immediately. And don't do it tomorrow. It always feels comfy to start your diet / workout / etc on a monday, or Jan 1, but that's bullshit. Just do something small, and something that's actually easy - clean your room, do some dishes, instead of videogaming just take a 10m walk around the block listening to music and clearing your head.
I think sometimes getting caught up in all the self-improvement frenzy people can feel a sense of anxiety if they're not spending every waking moment becoming Marcus Aurelius or Jocko Willink - but I think quiet time for meditation and reflection is extremely important in today's information overload world.
Anywho, at the end of the day, try and reflect on or write down any good deed you did that day. As simple as doing those dishes, or journaling your thoughts for a few minutes, or doing 25 pushups during a tv commercial. And then you try again tomorrow.
"Man is nothing else but that which he makes of himself" - so why not try and make yourself something you'd enjoy?
