Parus, I'm so glad that you refer back to the "Why bother?" discussion you started. Allow me to insert the link to it here:
- "WHY BOTHER?" What can we do when we are stuck? https://connect.mayoclinic.org/discussion/why-bother-what-can-we-do-when-we-are-stuck/

I especially like your question in that discussion asking for ways to get unstuck. You asked:
"...maybe some can share how we get out of a rut to help ourselves. We all get stuck stuck at times. Curious as to what others do when stuck in that thought mode of 'Why Bother?'"
