Dear 'Future Adi', I write to you from the past, December 15th - 2018 to be exact. You have had a "good" year, nothing too worrying. Completed 12 freelance projects, started work on 2 side projects (Laravel Links, Laravel Collections). All these would not be possible without the fabulous tools you used on a daily basis. The list is quite long but it's worth a look.
