"Idril had a great power of piercing with her
thought the darkness of the hearts of Elves and Men, and the
glooms of the future thereto -- further even than is the common

"his (Thingol) coolness does not appear
until his refusal to attend the Feast of Reuniting (Mereth Aderthad)

"He (Cirdan) is said in the Annals of the Third
Age (c.1000) to have seen further and deeper into the future
than anyone else in Middle-earth.(31) This does not include the
Istari (who came from Valinor), but must include even Elrond,
Galadriel, and Celeborn."
Elves DO think of the future.Many of them are seers and can actively see much into the future.Moreso the high elves how much the Ainur know of the future as much of it was open to see through the Ainulindale...
Even in the second age they start to build new things, new Realms... Nenduial, Harlindon, Eregion, Rivendell, Lorien, Edhellond...
Galadriel herself does most of it.
Yet, they do feel all of this will not last and they wish to preserve... to even conserve if necessary, yet only in places isolated from men as they continue to spread and grow more numerous...
