Think the 2nd monitor as a cheat sheet - and then it becomes useful when you code to solve a problem. Otherwise, I agree that watching YouTube and doing coding is counter productive - at least base on my personal experience - I got less done...

The crash is the result of over-speculation and other factors that in play such as new restriction, regulatory change, or security issues/hack. Like you said, spectacular return comes with spectacular volatility, you can't have one without the other one. Enjoy the ride while you still can.

In Agile, all you do is to deliver value to the customers. You organize the teams in the best way possible to fulfil that goal. It's not just project manager. Any role that doesn't help the value delivery should be questioned. It's mindset shift.

Over-engineering is bad. Period. It's costly and introduces complexity that you and the customers don't want to deal with.

On the other end, just because you think you cannot predict the future 100% correct, it doesn't give you an excuse to put no effort to do it. You don't ship into the ocean without a map.

Any company would experience some growing pains if it succeeds. As architects, our job is to do our best to predict the future and design an blue print that meets that predicted needs :)

A coupe things to remember.

1. stocks is the ownership of the company. Buy those companies that are strong in sales. Demand is a verification of the company's strength in products & strategies.

2. always pay attention to the valuation but take growth into account. Lagging indicator helps you understand where we are only when we see the business through forward-thinking lens.

3. timing matters only when you understand valuation and forward-looking thinking.

Thanks for sharing your advice based on your life experience. Another way to make decision is use hurdle rate instead of strictly speaking discount rate. There you can try to quantify happiness in additional to purely financial return.

My feeling is that PC and its app ecosystem is outdated and doesn't have leadership on what the future gonna look like.

When Apple announced that the M1 chip Mac can run iOS apps, I think it's the Game Over call to PCs - TBH, for avg users, mobile apps are much easier to use than most website or their PC software counterparties.

The cost to own a Mac could still be the barrier, but owning its own chip is a way to cut the manufacturing cost. Or, in Apple's way, to maintain a fat gross margin :) we'll see.

This sounds familiar to the idea of 4-hr work week. btw, it's a good reading. Highly recommended.
