Practise what you know, and it will help to make clear what now you do not know.

Exchange information, learn to speak sensibly about any subject, learn to express your thoughts, accept new ones, examine them, analyze. Think objectively. Think toward the future.

Sertillanges argues that to advance your understanding of your field you must tackle the relevant topics systematically, allowing your “converging rays of attention” to uncover the truth latent in each. In other words, he teaches: To learn requires intense concentration.

Learning to think rigorously, so as to act rightly and to serve humanity better.

You do not simply, mindlessly, implement the best practices. You have to think deeply about your condition. If the “best practice” seems like a useful countermeasure for your problem, you should learn from the best practice; however, what may have worked in some other place may not work for you without adjustment and even further improvement.

Try to put well into practice what you already know. In so doing, you will, in good time, discover the hidden things you now inquire about.

Learning what you know is something you have to do every day and every moment.

You have to know how to learn anything you want to learn.

To learn hard things quickly, you must focus intensely without distraction. To learn, in other words, is an act of deep work.

Si quieres ser sabio, aprende a interrogar razonablemente, a escuchar con atención, a responder serenamente y a callar cuando no tengas nada que decir.

Life will examine us continually to see if we have understood and have practiced what we were taught that first year of school.

Examine, inquire.
Look into the nature of things.
Search out the grounds of your opinions,
the for and against.
Know why you believe, understand what you believe,
and possess a reason for the faith that is in you.

Instead, you need to learn as you go, solving more and more complex problems. And with luck, learning the answers to your questions just in time.
