Drop and drop makes an inundation:

"A little and a little, collected together, becomes a great deal; the
heap in the barn consists of single grains, and drop and drop makes an
inundation." – Arabic proverb
:->
Do what good you can in this life and don't worry that it's too
little, or that it won't change things, or that you do not see
immediate results. Your contribution matters. The ripples spread
outward, even unseen, so that your presence on earth eventually
affects everyoneelse in the world.
Or, if you don't put stock in proverbs, then remember the words of
Allah in Surat Az-Zalzalah:
"Then shall anyone who has done an atom's weightof good, see it! And
anyonewho has done an atom's weight of evil, shall see it." (Quran
99:7-8).
Never listen to those who say that it's pointless to try,or that the
good work you are doing is hopeless. The tiniest bit of good you do,
matters. An atom's weight of effort makes a difference! It changes
things, whether you see it or not.
