For example, when we don’t feel like doing anything Bay Doctors, Auckland and would rather watch TV and have a drink of alcohol, we need to remember how we felt when we last went out or when we last did exercise. In most cases that would be a more enriching experience than drinking alcohol and watching TV. For personal pain, we need a different approach. We need to approach issues rather than avoid them, and hold negative thoughts lightly. Values and living with ease In the ACT model, we are not trying to make our negative feelings go away. Instead, we need to be pursuing our values (those things that are important to us in the long term). By attempting to approach our values (they are directions and not destinations), we can aim to live with ease. This is not the same as avoiding suffering, as we need to accept that suffering is expected and okay and not to fight it. Knowing your life dashboard warning light Getting to know your life dashboard light can be essential to recognise when you are starting to experience distress. In my own life, I usually like to go to the gym for a workout. When I start feeling stressed, one of the first signs is that I do not want to go to the gym (remember: life constriction accompanies mental health issues). I have learnt that when the dashboard light starts flashing, I now go straight to the gym and generally feel a lot better afterwards. In summary Recognise there is no delete button in the brain. Its role is to keep you alive and not forget negative things that have happened to you. Avoid- ance is the source of much of our human suffering. For personal pain, we need an approach modality and to learn to hold uncomfortable feelings lightly. When we get stressed, we need to keep our worlds expanded, keep in contact with our support people, and keep doing our recreational activities (including some form of exercise). Learning to trust your experience, not what your mind is saying, is a powerful skill to develop. Cultivating the voice of self-compassion in your mind is a skill worth learning. Speak to your mind with the tone of the personal trainer, not the sergeant major. Finally, please get to know your life dashboard warning light, and take action when it comes on. References 1.

In this approach, the amount of time recommended in bed is estimated by References calculating the average amount total time spent actually asleep per night.
