Holy shit this thread is for me. I keep a list on my door and add to it daily.
Seeing the sunrise or sunset
Someone enjoying your cooking
Hot chocolate on a cold and bitter day
Singing to a huge imaginary audience
Waking up to realize your cold has passed
Beating an exercise record
Helping someone if they're short on change
A song that's perfect for how you feel that moment
The perfect high-five
Learning something new
When someone changes their opinion because of you
Finishing a book or movie
Putting the last piece in a puzzle
Opening a present
When someone laughs at your joke
A cool breeze on a really hot day
Taking your pants off
The perfect cup or tea or coffee
Checking the spelling of a word to see you already spelled it right
Complimenting someone and they smile
Letting a pedestrian cross
The moment of silence after a good song
Jumping in a puddle and not caring if you're wet
Running through leaves
Mowing the lawn
The clean feeling after brushing your teeth
Buying someone flowers
A clear blue sky
Finally opening a tough jar
Seeing something you were going to buy anyway is on sale
Reaching the top of a hill
Doing something someone told you you couldn't
Solving a problem
Remembering something that was on the tip of your tongue
Singing with someone else
Seeing a happy old couple
Jump starting a car on the first try
Getting out if bed as soon as the alarm rings
Pushing out one more rep
Opening the door and the fly flies out
Hitting a string of green lights
Walking on a moving walkway so it feels like you have super speed
When the lift goes straight to your floor
Getting into a bed with clean sheets
Putting your hand in a really clear river
Washing off make-up
Saying no to junk food and eating right
The sound of dirt going up the vacuum
The smell of clean washing
Doing something even though it scares you
Leaving a situation better than you found it
Putting furniture together successfully
Waking up after a good nights sleep
Finding a pair of jeans that fits just right
Throwing something into the bin from far away
Parking perfectly the first time
Mixing the right colour when painting
A perfectly cooked steak
A quick download
Having the exact change
An awesome day dream
Watching a plant you cared for flourish
If you pet comes when it's called
Finding money in your pocket
100% charge
When someone says what you were thinking
A good hug
When everything fits back into the box it came out of
