When you take responsibility, you experience the achievement of your personal success goals at a much higher level than if you take credit only for your successes and blame someone else for the rest.
This will become the “baseline” from which you will measure your physical and mental progress.
You can ask your friends, your family or even your co-workers, as they all watch you and are affected by the things you do and will therefore have some opinions about your abilities.
Next, dedicate yourself to writing a series of goals for your future in which you lay out in detail what you want your life to look like three years from now, one year from now, and what you will do each week to get there.
Once you have committed to making a change or learning how to do something better, you can use various self-help books or online courses to learn how to make this change.
Start in your own personal development and self-improvement by taking small, manageable steps in the direction of your dreams, no matter how small they may seem. Get to know yourself.
