Every endeavor that we set upon starts with an idea. The invention of the wheel, the design of computers, the first trip to the moon. All of these started out as an idea before becoming a reality. This is why it is so crucial for you to have a sense of who you want to be in life if you're going to find success and happiness.
The mindset that you embrace is more important than your people skills, more important than your abilities, and more important than any other competency you may currently have or that you may develop in the future.
Your mindset is what will allow you to achieve your dreams and accomplish your goals. It can help you improve your surroundings, allowing you to become a happier person, attracting more positive people and situations to your life.
