The Next Level. A Book for Those Who Have Reached Their Ceiling

A book for those who have already achieved much but want to rise to a qualitatively new level of development.
Let's say, by thirty, you already know how to build a call center in Tver with a thousand operators, play the... Ponziani debut in a chess game, and change a kitchen faucet. All of this is your competencies. Although not all of them can be monetized, they can all be useful in different circumstances. We accumulate competencies throughout our lives, but the key, defining knowledge and skills are acquired between the ages of twenty and thirty. Why not earlier?
Because it is only around twenty that we begin to understand what we want to do. Before that, we somehow cannot figure it out (however, for some, it remains unresolved until retirement). Why not later? Scientists have calculated that ten thousand hours of practice enable a person to become a master in any field, whether it’s programming, playing the cello, or heavy machinery engineering. It takes roughly ten years to accumulate those ten thousand hours of practice.
And then, any successful person faces the task of moving to a new level - and doing something greater. Something even more significant. Usually, this can only be achieved together with other people, combining your capabilities with the capabilities of these people. Therefore, by the age of thirty, the importance of connections becomes critical.
Because by that time, the potential of personal qualities and competencies is exhausted. And connections, on the contrary, begin to play a decisive role.
