Anyone who has used Microsoft Word for a reasonable amount of time will recognise my very own Andy's Laws on Word:
Simple course in TeX
by Lakedaemon on Mon 6th Jun 2005 22:27 UTC

TeX is [u]easy[/u]. It takes 2 days to learn and 2 weeks to a become a proficient journeyman...

Of course, you rip the benefice of this for Life...

You gain time, when you use TeX instead of word to type formulas like :

"the integral from 0 to 1 the function (1 divided by 1 plus x squared) of the x variable is equal to pi."

[u] The previous text, in TeX code would look like[/u] :

TeX is \$underline{easy}\$. It takes \$2\$ days to learn and \$2\$ weeks to a become a proficient journeyman...

You gain time, when you use TeX instead of word to type formulas like :
\$\$
int_0^1{1over1+x^2}dx=pi.
\$\$

Explanations

\$maths\$ = math mode between two \$ symboles
\$\$maths\$\$ = the same but in beatifull formula mode
TeX = a core macro that writes TeX with eyecandy
underline = core macro to underline
medskip = macro to skip a bit vertically and indent
{bf expression} = the expression is written with Bold Face
int = integral symbol
^Someting = overscript something
_something = subscript something
{exp1over exp2} = writes the fraction exp1/exp2
pi = the greek letter pi

There...if you have read that, you know 50% of what you need to know to type in TeX
