Just is a pretty useful adverb. It can carry several different meanings:
- very recently: I just finished the novel.
- exactly: That’s just what he meant.
- by a narrow margin: He just missed me with the snowball.
- only: Bob was just a dishwasher until he met George Lucas.
- quite or very: The weather is just beautiful.
- directly: Just west of here.
- perhaps or possibly: Your plan just might work.
(With thanks to Dictionary.com and Merriam-Webster Online for these examples.)
There are also a variety of phrases using just, including just so and just about. I’m sure I haven’t covered everything here.
I’m curious about how we got all these adverbial senses of just. I checked the Online Etymology Dictionary for just and found this:
just (adv):
“merely, barely,” 1660s, from Middle English sense of “exactly, precisely, punctually” (c.1400), from just (adj.), and paralleling the adverbial use of French juste. Just-so story first attested 1902 in Kipling, from the expression just so “exactly that, in that very way” (1751).
How the heck did the adjective just spawn such diverse adverbial meanings?

You'll probably be disappointed, but the adverb does not have so many different meanings: words that express a general idea take (apparently) different meanings in different contexts.
Take for example long : it mean 'extended' and has a different meaning if you refer it to time or to space.
just expresses the general idea of
"It is impossible to say just what I mean!" (T.S. Eliot) or, more loosely,
space :
"...They had been standing just by the door..." (Thomas Hardy)
quantity:
"It is ridiculous to think you can spend your entire life with just one person" (The Observer), ( "Bob was just a dishwasher until he met George Lucas").
time:
"Alice was just asking Noel... when she heard..." (E. Nesbit), "I think I have just swallowed..." (I. Murdoch), "Tell his excellency I am just a coming" (D. Defoe)
It is as simple as that!
(the examples are from SOED)
I have indicated just one meaning, if you reflect just a bit, you'll see no contradiction between exactly (neither more nor less, quite,.. etc) and almost exactly (a little more/less... etc), it is only approximation, which is a natural feature of language. Bearing this in mind, you'll be able to clarify all other optical illusions. I didn't list all possibilities because it is not a closed list.
