We won 1st place & 50k in credits for @river_ai_inc at @ycombinator own your intelligence hackathon?!! We were there to mostly have fun and experiment, but ended up finding River super useful to solve a small problem I run into daily: my Claude/Codex never speaks like me!!! No matter how much context I give it, getting it to learn my vibe and vocab is sooo hard. So I used River to fine-tune Qw

And this marks the end of out 4 weeks at @fdotinc building @try_maglev I made a lot of mistakes. not from the things I did, but the things I could’ve said and done. I learnt a lot of a things. 3 things mainly: agency, clarity of expression, and execution. Remember so clearly after the first OH @Jonnysdoes said he “just knocks at doors”.

stuck in traffic 1AM, decided to write down some recent thoughts - real automation is the automation that works. pursuit of ‘e2e solution’ is only beautiful when every part works super well and well together. the best automation I’ve built starts incredibly small - encouraging people understand ambition and be more ambitious- I want to be doing this - patience is the key to life. it’s hard to d

time is really the only thing we need.

Mon, 21 Sep 2026 04:07:46 GMT

time is really the only thing we need. almost everybody has a certain amount of time that they could freely allocate. time is objective that no matter what you do, you could only experience certain things within a time frame. nobody could yet duplicate, manipulate or prolong the length of time. realistically speaking time is unidirectional. in relativity this might not be true, but generally ti

Tonight I messed up a client call and I felt like I’m not being respectful to their time, everything that could go wrong went wrong. I didn’t make the right call.

I don’t understand why pitch deck still exists for early stage investing All you have to do: see the product in use, talk to the founder(s), and work with them Lets be honest everybody could make pretty slides after certain amount of training and design/content could be outsourced - back in highschool I used to make money by helping teams design pitch decks Decision making should be only driven

recent thoughts all the em dashes are typed by me these two weeks at f inc have felt magical. I keep learning that there are certain things in life I can’t control. What I need to do now is to run into those things more aggressively. Learn to change what seems unchangeable, learn to let go when I can’t control something, and learn from the feedback. I don’t like to fail - if I can win (well,

I realized how much I dislike experiences that are flat, patterned, unremarkable. They leave an itch, a low buzzing annoyance, somehow harder to sit with than pain that is sharp and clear. When I feel terrible I think through the worst case and find it isn't that bad. It goes like this, then like that, then this again, and then it's over. The me at fifty won't remember one small hurt.

A hazy Sunday. In the morning I got up, took a group photo, hugged my friends who were leaving the house, toasted myself a slice of bread and laid two pieces of salmon on it to tide myself over, and swallowed a few feelings down along with it. I tried to work on the couch and failed, too sleepy for it. Heavy with drowsiness, I decided I simply hadn’t slept enough, and napped again for more than t
