For the last couple of decades it wasn't really necessary to know about a lot of different things.
It was usually enough to know a lot about one thing only.
To be really good at one thing.
It was the era of the expert.
The cost of not knowing things wasn't really high.
The cost of not having a diverse set of skills wasn't really high.
It was the time where you had to focus on one thing only.
It was the era of the specialist.
If you were really good at one thing corporations took care of you.
Really, really good care...
Unfortunately, for the expert and the specialist, times are changing.
Most experts and specialists aren't really needed anymore.
Sure, a really, really small group of specialists and experts are still needed.
And will always be needed.
But what's needed more and more, not only from a corporation's perspective, but also from your own personal perspective is the ability to build something out of nothing.
Incumbents are struggling to reinvent themselves.
They need more and more people who are able to build something out of nothing.
Jobs are disappearing or about to disappear and we don't really know when, whether or in what form these jobs will ever come back.
That's why it's so important to be able to go from specialist to generalist.
To know about as many different things as possible.
To have a broad set of skills.
The cost of not knowing things increases every single day.
The cost of not being able to build something out of nothing increases every single day.
This is probably one of the biggest challenges but also opportunities of the 21st century.
Being able to properly manage your costs of not knowing things and investing time and resources into the right things to know…
