My Favorite Habit
I've got a lot of habits. Some are good like Duolingo (+700 days and counting!) while others are bad, like compulsively checking my phone (working on it). However, I have a favorite habit and something I recommend to a lot of my friends.
The habit: write your loved one a card once a week, but save them and give them all at once (birthday or holiday or anniversary).
It's quite a simple habit. I have a blank pack of postcards. Every Wednesday, a reminder pops up for me to write my wife a card. So I just take five minutes and write about what we've been doing, what we are looking forward to, and what I appreciate about her. Then on her birthday and Christmas I give her what I wrote down.
I really like this habit because it's practially no work on a weekly basis but the result is absolutely greater than the sum of the results. It's so much fun to read through what I had written and what was going through our minds as a couple.
