"My Mind to Me a Kingdom Is"

I've been extremely unhappy for a good bit now, and I know that it's all in my mind. It's my view of things that causes all my distress and malcontent. I want to internalize this poem...

My Mind to Me a Kingdom Is My mind to me a kingdom is; Such perfect joy therein I find That it excels all other bliss Which God or nature hath assign'd. Though much I want that most would have, Yet still my mind forbids to crave. No princely port, nor wealthy store, No force to win a victory, No wily wit to salve a sore, No shape to win a loving eye; To none of these I yield as thrall,-- For why? my mind despise them all. I see that plenty surfeit oft, And hasty climbers soonest fall; I see that such as are aloft Mishap doth threaten most of all. These get with toil and keep with fear; Such cares my mind can never bear. I press to bear no haughty sway, I wish no more than may suffice, I do no more than well I may, Look, what I want my mind supplies. Lo ! thus I triumph like a king, My mind content with anything. I laugh not at another's loss, Nor grudge not at another's gain; No worldly waves my mind can toss; I brook that is another's bane. I fear no foe, nor fawn on friend, I loathe not life, nor dread mine end. My wealth is health and perfect ease, And conscience clear my chief defence; I never seek by bribes to please, Nor by desert to give offence. Thus do I live, thus will I die,-- Would all did so as well as I!
