Can anyone suggest me letter of motivation for Phd in computer science.my research work is based on neuroscience and computers applications

Dear self

I promise you that when I submit this thesis, I will:

-go on holiday for three weeks without giving a damn about the department

-go to the gym and get THE BODY

-make sure I spend plenty of time with my other half

-buy a new gadget: the latest computer out there (and read anything but the thesis)

Regards

Self
