The most important skill to becoming rich is to be a constant learner.
Whatever you want to learn, figure out how to learn it.
The old way to make money was to go to college for four years, get a degree, and then work in a professional field for 30 years.
But things changed quickly.
Now I have to adapt to a new job within 9 months.
Because after 4 years it will be of no use.
But if you spend three years productively, you can become very rich.

In business relationships, it is very important to increase your well-being.
Look at the people who play the most important roles in society, such as why some people become executives of public corporations or sit in positions that control billions of dollars.
It's because people trust them.
They are trusted because they have built relationships and performed work that has benefited others.
Not only was he dedicated to the company he worked for, he also demonstrated high integrity in a visible and responsible manner.
There are also benefits to your reputation.
If you have a great reputation and have been building it for decades, people will quickly figure out what kind of person you are.

When we do something, the less we want from it, the less we think about it and the less we are obsessed with it, the more naturally we can do it.
And you do it only for yourself.
You become dedicated to doing it the way you are good at.
As you do this, people around you will notice that you are working with more dignity.

If you have specialized knowledge, responsibilities, and leverage, the company should pay you what you're worth.
If the company pays you what you're worth, you might be able to get your time back.
Then your efficiency will increase tremendously.
There's no need to have meetings for the sake of meetings, no need to try to impress others, and no need to write things down to make it look like you've done some work.
The only thing you have to worry about is the work itself.
If you focus solely on the task itself, you will be much more productive and efficient.
You only need to work when you feel good, that is, when your energy is high, and you don't need to force yourself to work when your energy is low.
That's what it means to get your time back.

Another way to think about whether something is worth doing yourself is that unless it can be done for less than your hourly wage, you might as well outsource it or not do it at all.
If you can hire someone to do the job for less than your hourly rate, hire them.
This also includes tasks like cooking.
You may want to eat healthy meals cooked at home, but if it's more advantageous to outsource, then do so.

If you feel aversion to wealth, it will prevent you from becoming rich.
Because you don't have the right mindset and the right spirit about wealth, you won't be able to deal with people at the right level.
It is important to always be optimistic and think positively.
In fact, optimists get better results in the long run.

To become rich even when luck is not ours, we must develop the ability to make our own decisions rather than leaving fate to chance.
We must not leave our fate to chance.
--- p.81

Everyone wants to become rich instantly, but the world is not an easy place.
There is no instant success.
It takes time.
You have to invest a lot of time.
To become the world's best in your field, you must be equipped with specialized knowledge, responsibility, leverage, and your own true skills.

I define wisdom as 'knowing the long-term consequences of your actions.'
Wisdom applied to external problems is judgment.
Because we need to know the long-term consequences of our actions so we can use them to make the right decisions (judgments).

If you have something to criticize about someone, don't criticize the person, but criticize their general approach or type of activity.
On the other hand, when praising someone, always find the best example of what they deserve and praise them specifically.
Then their pride and identity will work to your advantage.

It doesn't really matter what book you read.
If you read books that interest you, you will end up reading a lot of books.
Just doing that will dramatically improve your life.
It's the same principle that exercising a little bit every day and having fun is the best exercise for you.
So, read not only books, but also blogs, Twitter, anything that gives you ideas, information, and something to learn.
The best way is to find a field you like and read it all the time.

The more I am present, the happier and more fulfilled I feel.
I'm stuck on some emotion and I'm like, "Oh, I'm happy now.
If you say, “I want to be happy,” you will be far from happiness at that moment.
And then suddenly your mind will be moved and you will want to attach yourself to something else.
Because our minds try to create permanent situations out of temporary ones.
For me, happiness is not suffering, not being greedy, not thinking too much about the future or the past, embracing the present moment and accepting reality as it is.
--- p.125

Desire is a contract you make with yourself to be unhappy until you get what you want.
Most of us don't seem to realize what desire is.
We spend all day craving something and then wonder why we are unhappy.
I try to keep aware of what I long for.
Only then can I choose my desires carefully.
I try not to have more than one big desire in my life at any given moment.
And I recognize that desire is the axis of my suffering, and I realize what areas I have chosen to be unhappy in.
--- p.134

The most important secret to happiness is realizing that happiness is a skill we can develop and a choice we make.
You can choose and work to be happy.
It's the same principle as building muscle, losing weight, becoming successful at work, or learning calculus.
If happiness is important to you, make it your top priority.
And read everything you need to know about the subject.
