| 5. Planning and organizing daily life | Problems with planning an organizing sequential behaviour often result in situations where adults with ADHD do several different things at the same time, feel pressurized, and end up finishing none of their planned tasks.

This module presents stress management techniques, how to handle a tendency towards procrastination, breaking down large tasks. Based on CBT. |
