(6. (JIRA users) Distinguish your JIRA issues from your personal to-dos.
If you’re a JIRA user, you’re familiar with using issues to plan, track, and report on your work. Your JIRA issues are items set for the whole team to view. But, your to-dos are personal items you set yourself in order to record an idea, achieve a goal, or finish a project. If you incorporate a to-do list with JIRA, you can write to-dos, ideas, reminders, and steps that only you need to know about, and still directly connect them to an issue in JIRA.)
How would i do that? Create a seperate project and only assing myself permissions?
