Adopt a creative approach towards everything

Be receptive to new ideas.
Never reject an idea straight away, even if it sounds silly. Take it in and let them sprout in your mind.

Experiment with new things more often.
Expose yourself to fresh places, books, and do something different every day. New experiences increase cognitive flexibility and the depth of your thoughts, helping you expand your raw creativity.

Practice asking and listening.
We learn nothing from telling. But there is no limit to what we can learn by asking and listening. Ask creative questions and you will get interesting answers.
