I know I already posted about the joys of getting a holiday card, and how it's like unwrapping a surprise gift (which we rarely get as an adult). Well, you know another form of that that doesn't have to wait for the once-a-year moment? Sending a thank you note. Yes, a hand-written Thank You card is always great, but even a thank you text or email - letting someone know what a great job they did - means the world. Feel like going the extra mile? If it's work related, send the compliment to that person's boss and blind copy (e.g. BCC) the person. It's rare that a boss hears the 'good' things. Most of the time when they are looped in it's because of complaints. So this has the added benefit of helping the person out (1) work wise b/c their boss now knows they did something appreciated and (2) personally, because people do more who feel appreciated.
Hopefully you get a chance to thank someone soon. And even maybe get one yourself! Cheers!
