I'd like to recommend giving Daylio [1] a try if you want to start journaling. Someone on HN recommended this two years ago and I decided to try it because all past attempts at journaling had failed miserably after few weeks. I'm now on a 700+ day streak and I'm really happy that I started doing this 2 years ago. So much has happened and it's all documented. It takes so little effort to add an entry for the day and reading past entries is fun because what actually happened past year is not just a blur but a detailed record of activities, words and photos.
