Hey Divyansh,

It really made me think. Here’s what came up:

1. From “I’m just a guy who can sell” to “I can build and run a global software business”. Took years to change.
2. From “This is ⅓ of the product and should not enter the market being so incomplete” to “This is ⅓ of the product but ok to enter the market if customers find it useful as is, we’ll just continue developing while being used.” I needed other co-founders to convince me that it’s a good way forward, and it sure looks like it was 🙂.

There were others I’m sure but I guess less harder to change then, I’m happy to change my mind and habits 🙂.

Don’t know if it helps but that’s the hardest one to reflect on for me at this point.
