Hi Frotzwolf,
I believe it would be great if you can list down things that you need to do and allocate them into 4 categories,
1. Important and urgent,
2. Important and not urgent,
3. Urgent but not important,
4. Not important and not urgent
Once you had this list, you can then do a weekly plan to allocate time to clear up the tasks.
I had wrote an article which is more extensive, you could read it and hope it helps.
