How to become a better person than yesterday
It all starts with one simple phrase: "If I want to, I can do it!"

Regardless of age, everyone has a dream, a vague expectation, and a desire to become a better person.
Think about it.
Doesn't this inner voice grow louder every time a new year approaches, every birthday, or every time you visit a bookstore? There are probably quite a few people who buy self-help books, place them on their shelves, and simply look at the titles, believing they have hope.
The problem is that every time we commit to putting it into practice and changing our habits, it seems like too much of a stretch.
Haven't you been putting off things that require your full time, only to check your schedule and eventually say, "Oh, I'll do it later!" because you don't have the time right now? As a result, your life becomes dull and dull, and you often find yourself stuck in a cycle of self-justification, unable to change.
Not only that, but as excuses become a habit, you will often clash with people around you.
Psychology is a useful tool for breaking out of these frustrating patterns.
Psychology says:
I firmly believe that I can become a better person and use psychology to do so.
If you change your thoughts based on psychology, you can change not only yourself but also the world.
So, embody psychology every day and repeat to yourself, 'If I want to, I can do it!'

33 Psychological Habits of a Mature Adult

This book is the latest work by Liu Xuan, author of the best-selling book, "Psychology Can Be This Useful," and begins with the belief that "I can do anything I want!"
Of course, this belief must come from confidence built up step by step through 'small successes in everyday life,' and to achieve this, he says, five steps must be taken.


STEP 1: Understanding the Psychological Motivations Behind Your Behavior
STEP 2: Set Your Intention for Change
STEP 3: Correcting Behavior
STEP 4 Check the effect (if it seems effective)
STEP 5 Try until you succeed

This book encourages us all to build confidence through "small successes in everyday life" and, furthermore, to believe that "I can do anything I want!"
This book is great to read in the morning, on your commute, or before bed.
It's designed so you can read a single page in the time it takes to pass two or three subway stops, so take advantage of any spare time to explore psychological interpretations of various problems in your life.
Let's also apply the practice methods summarized in each chapter to real life.
As dust gathers, a mountain becomes, and as water drips, it wears away the stone.
If you want to become a better version of yourself, try adjusting your brain waves toward 'getting along well with yourself' through the 33 psychological habits in this book.
If you keep telling yourself, "I can do anything I want!", little by little, those words will turn into actions and result in results.
