If you want to be happier and improve your life quality, you should immerse yourself in subjects that you wish to learn more about
Consistently engage with the right kind of information so you can continue to grow
But you also need systems to learn new skills quickly.
Study - Practice - Teach comes into play here
When you are studying, you are learning and thinking about the subject
The same goes for when you are practicing a subject
And when you teach, you learn twice
Seneca said of "Study"...
"If you apply yourself to study, you will avoid all boredom in life; you will not long for night because you are sick of daylight, you will be neither a burden to yourself nor useless to others, you will attract many to become your friends and the finest people will flock to you"
Seneca is talking about applying yourself to the study of a craft
It doesn't matter what the craft is, but if you specialize in an area or several different areas, not only will you be useful to the people around you, but you will also be helpful to yourself in your own life.
Practice is about putting into action what you have studied
Epictetus tells us...
"That's why the philosophers warn us not to be satisfied with mere learning, but to add practice and then training. For as time passes, we forget what we learned and end up doing the opposite and hold opinions the opposite of what we should."
Epictetus is saying that learning is not enough; implementation must follow
If we want to turn all that study into something more tangible, you must take action and put it into practice.
I would even go so far as to say this is the most critical step in this process.
Seneca had wise words about Teaching...
"Associate with people who are likely to improve you. Welcome those who you are capable of improving. The process is a mutual one: men learn as they teach."
If you surround yourself with others who want to improve, you will naturally help them, and they will do the same for you
It's a teaching circle of direct and passive teaching, both of which are important and necessary for continued growth and development.
Study - Practice - Teach is a sequential theory
You start with STUDY and learning
So you can understand how to apply and then PRACTICE what you have learned
Then you can TEACH this knowledge, whether it is passively or directly, to others.
Keep studying and finding subjects that interest you
When you find something you want to know more about, practice it, and share your experiences, whether directly or by example
Following these steps will help you learn and apply ANY skill quickly
