Desiderata (Latin: "desired things") 
1927 by American writer Max Ehrmann (1872-1945)

Go placidly amidst the noise and haste, and remember what peace there may be in silence. 
As far as possible without surrender be on good terms with all persons. 
Speak your truth quietly and clearly; and listen to others, even the dull and the ignorant; they too have their story.
Avoid loud and aggressive persons, they are vexations to the spirit. 
If you compare yourself with others, you may become vain or bitter; for always there will be greater and lesser persons than yourself.
Enjoy your achievements as well as your plans. 
Keep interested in your own career, however humble; it is a real possession in the changing fortunes of time.
Exercise caution in your business affairs; for the world is full of trickery. 
But let this not blind you to what virtue there is; many persons strive for high ideals; and everywhere life is full of heroism.
Be yourself. 
Especially, do not feign affection. Neither be cynical about love; for in the face of all aridity and disenchantment it is as perennial as the grass.
Take kindly the counsel of the years, gracefully surrendering the things of youth. Nurture strength of spirit to shield you in sudden misfortune. 
But do not distress yourself with dark imaginings. 
Many fears are born of fatigue and loneliness.
Beyond a wholesome discipline, be gentle with yourself. 
You are a child of the universe, no less than the trees and the stars; 
you have a right to be here.
And whether or not it is clear to you, no doubt the universe is unfolding as it should. Therefore be at peace with God, whatever you conceive Him to be, and whatever your labors and aspirations, in the noisy confusion of life keep peace with your soul. 
With all its sham, drudgery, and broken dreams, it is still a beautiful world. 
Be cheerful.
Strive to be happy.

There are two equinoxes every year – in March and September. 
The Sun will rise due east and set due west on the equinoxes (on all other days the Sun will rise either north or south of east, and set north or south of west)
The length of day and night are nearly equal (No need for exact maths on this page)

1. SEPT - Autumn Equinox = equal day/night
2. Night increases , Daylight decreases
3. DEC - Winter Solstice = shortest daylight/longest night - northern hemisphere tilts away from sun so least exposure to sun and shorter days.
4. Daylight increases, Night decreases until ..
5. MAR - Spring Equinox = equal Day/night
6. Daylight hours continue increase until..
7. JUNE - Summer Solstice = longest daylight/shortest night - northern hemisphere tilts towards sun so gets max daylight.
8. Daylight decreases until... Goto 1.

Without the earths axis tilt it would be equinox all the time and we would have no Winter or Summer.

Back to skool for the overall picture: 

....and for those who want to sing-a-long-a-science:

nb. Disclaimer - As with all science if you go into it at a professional level you find the above is so basic that it is almost misleading, but without the above framework it would be practically impossible to really understand the movement of the earth around the sun at a higher level. (-:
