when the brain is fighting

I guess all of you have this experience.
talking to yourself with the separation of brain into 2 parts and start fighting with each other.
When i am tired and not able to continue the task, i say " give up! still can have other solution"
but my very rational brain tell me to continue it, you shouldn't disappoint those care for you.
the brain start fighting!

This is the critical time for me to make a decision.
Some will use a coin to make the decision.
Some ask for more advices for this.
Some stick to old plan, lazy to take a change.
Some will try something different.
