Solution

Break down complex experiences. Split content into smaller parts making each portion easier to digest.
Indicate progress clearly. Provide a clear indication of progress in order to motivate users to complete the full list of tasks. The task list can originate from a larger broken down task, but also an artificially created list of tasks to “complete onboarding” or “finish setting up the project”.
Reminder to finish. An interrupted or incomplete task leads to a strong motivation to complete the action. Find ways to remind users that they have unfinished business and show them ways to finish it.

Rationale

The Zeigarnik effect suggests that when we suspend our work on a task to perform unrelated activities, we will remember the details of the first task better than people who complete it without a break.
