If you're building something for someone.
Try to put yourself in their shoes.
You're not a leader seated atop a thrown in a high castle somewhere in a distant land, looking down upon your gentry, and telling them what's needed.
Or maybe you are?
If you're building something for someone else:
Walk a mile in their shoes.
Understand what keeps them awake at night.
Know the things that make them come alive.
Have a vision for what they're trying to achieve.
See the world through their eyes.
Develop an impression of how they came to be where they are today - what was their journey?
Know who they are for! Who are they trying to help?
What is their "something better"?
You can't speak to someone until you learn to see them.
That requires empathy.
It's simple.
