Question everything:

You have to ask. Don't assume anything or subscribe unthinkingly to the conventional wisdom. Keep your eyes and mind wide open. The greatest enemy of knowledge is not ignorance but the illusion of knowledge--and questioning and curiosity are the key to overcoming it.

Continue Your Education:

you have to continue your education. Adult education is one of the best investments of time, money, and energy you can make. While education is valuable throughout childhood and adolescence, adults often underestimate their ability to learn new concepts and skills. Challenge yourself to take a class, academic or creative. Voluntarily choosing to continue education provides a perfect opportunity for your brain to create new connections and build higher intelligence.

Think of new ways to do old things:

You have to think of new ways to do old thing. To be innovative means making creativity more important than the fear of being wrong. Even in the things you do every day, you can be inventive and experimental. When you take risks, make mistakes, and have fun instead of slogging through the same routine. You'll have a daily reminder that imagination and creativity can change the world.

Challenging Yourself:

You have to challenge yourself to do batter. Like a weightlifter who develops muscles, one must exercise the brain on a daily basis, pushing it just beyond its current capabilities. As Albert Einstein once said, “One should not pursue goals that are easily achieved. One must develop an instinct for what one can just barely achieve through one’s greatest efforts.”
This quote encapsulates what I believe about the brain. With enough focus and stretching, the brain can truly surprise people. Underestimating yourself holds you back from success. When people begin believing in their abilities, they often go beyond what they thought was possible.

Share what you know:

You have to share what you know. Learning something new is important, but sharing that knowledge makes what you've learned actionable and meaningful.
