Thats the lesson you learn in life . But anyone starting their career will have a tendency to under promise, over deliver. I did this for some time until my manager told me to literally to go slow and deliver quality work instead.
And if you're getting started today in investing -- it's always a good time to invest. If you think that 10 years ago you should have invested in X, then in 10 years from now you'll be thinking you should have invested in Y.
For example -- buying BTC is a bit expensive today and will likely be more expensive in the future. You could buy 1 BTC today and hope that it goes up significantly in the future. OR you could look at Ethereum and realize that it's in a similar place to BTC and that in 7 years from now you may be wishing you had purchased it today.
Yep, there are probably several thousand ARKit-compatible iPhones to every 1 Tango tablet in use out there. Tango's basically not a launched product, just a bunch of developer kits.
The primary factor being proximity to other people in the same industry is dramatically higher, and jobs within the computer industry in Silicon Valley are so much more dense than any other place on the planet. The joke in SF is that you can't walk 5 feet without running into a programmer or a startup founder. Go to anywhere else in the world and there are comparatively a very small number of programmers/startup founders.
In LA you have something similar with movies -- most people are aspiring actors and there are many people in filming and sets. However, working as a programmer in LA versus SF is very different -- there are a lot fewer engineers and entrepreneurs here per mile than the Bay Area.
It comes down to proximity to people of the same talent set. Where are the people who are good at X living? That's where X is thriving. If suddenly all the engineers left Silicon Valley, it would no longer be a tech hub.
That would be interesting. Imagine if there was an audiobook version of Pandora. Randomly a book chapter jumps in and starts playing. Skip. Then another. Like what you're hearing, swipe right to add to your "explore" library. Swipe left to get rid of it.
