Have multiple opinions

Accept that one perspective can narrow your imagination.
Recognizing that having just one solution for any problem is wrong. You have to debate with yourself sometimes.

Test your ideas.
When someone has a different viewpoint than yours, try to test your ideas on them and find out the weaknesses of your concept.

Be curious.
Instead of arguing your case, try to understand the other’s perspective to see if there’s something you have never considered. Be open-minded.

Don’t be a hammer.
A hammer only sees a nail, while a toolbox fixes multiple things. Use handy instruments to shape your beliefs.
