Send Thanks to Unlock Unexpected Doors

You arrive at the co-working café feeling behind on deadlines. The barista hands you your usual latte with a knowing smile and says, “Made it extra frothy today.” A small gesture, but it brightens your mood. Later that day, you recall fellow investors at the Yellow BRKers gathering and how helpful one emailed you a research link. You grab a thank-you card and write, “Your tip on that annual report saved me hours—thank you for thinking of me.” You drop the card in the mail, amused at how easy it felt.

The next morning, you get a message from the barista: “I’m so glad you noticed the foam!” That ripple of warmth carries you through two intense meetings. You also receive a quick reply from the investor, promising to share more resources. You realize that one small act of gratitude can expand your network and boost your mood.

Psychologists call this the “liking” principle—people reciprocate when we acknowledge them sincerely. Gratitude also rewires our brain’s reward system, making us happier. When you write those five notes this week, watch how your world shifts.

This week, pick five people—could be your manager, your trainer, or even the café staff—and jot down one genuine reason you appreciate each. Write a short card or email immediately, using a three-sentence format: a warm greeting, your specific thanks, and a personal sign-off. Drop them in the mail or hit send by Friday. Notice their smiles, replies, or small gestures. Keep a folder of sent notes so you see the ripple effect. Start today, and watch your relationships—and your happiness—grow.
