It is very common for someone to ask, “How much time will it take for me to learn X or become like Y?” Here is my take - stop measuring how long something takes to learn and start measuring what it takes to get there.
When someone reaches a skill level, they did not just spend time. They put in effort to get there - hours of practice, attempts, repeated correction. That effort is the real unit, not the clock.
If you want to learn X in less time, operate with high intensity, and concentrate the effort into less time. If you spread the same effort across more time, you can lower the intensity and still arrive at the same place.
This is why “it took them 2 years” is a useless benchmark on its own. Two years at 1 hour a day is not the same effort as 2 years at 4 hours a day. The duration tells you nothing without the intensity behind it.
So the real question is not “how long will this take me?” It is “how much effort did this require, and how much intensity am I willing to bring?” Once you know the effort, you can choose your own pace.
Compress it with intensity, or stretch it with patience. Either path gets you there, but only if the total effort adds up.
Hope this helps.
