For those who take themselves too seriously.
1. Use a font that's just a little bit too big. You want to make sure your list looks like it was written by a 19th-century aristocrat.
2. Add a few unnecessary subheadings. It adds to the pretentiousness, darling.
3. Use words that are just a little bit too long. Like "effervescent" instead of "bubbly."
4. Make sure your list is asymmetrical. It's just so... artistic.
5. Use a font that's just a little bit too fancy. Like "Comic Sans" or "Impact."
And remember, if you want to be truly pretentious, you must always...
Use snooty slang to describe your to-do list items. Write passive-aggressive notes to yourself. Develop sophisticated snooping techniques to monitor your coworkers' productivity.
