The best way to achieve success is personal growth, which occurs through self-knowledge, constant striving for self-development and professional improvement.
Yes, it may not seem very motivating, but personal development contributes to an increase in the standard of living, which, of course, will affect the implementation of goals. It's a long journey without a final destination, where the results will change not only the way you see things, but everything you thought and knew about yourself.
Personal development is a lifelong process. This is a way to assess your skills and qualities, to revise your life goals, aimed at realizing and increasing your potential.
You need to define goals in life that can ultimately improve your performance at work, build confidence, and lead to better quality of life and satisfaction. Plan to make the right and effective life choices for your future to ensure your personal development.

When it comes to personal growth and development, you need to know that they are not the same thing. Because they occur at different moments of our conscious life, when we are really looking for a path to success and development.
It may be that a person grows, but never develops. Conversely, in this case, personal growth can occur both intentionally and unintentionally. That is, as a result of personal development or external circumstances. But only personal growth, as a rule, strongly affects the personality, because, as you grow up, your worldview also changes. You can say that you become a "new" person, but not everyone will be able to accept this, and this is normal.
