Incase you are in the habit of complaining, I think you should take a pause and thank God instead.
That thing you complain about, someone else wished they have it,
That thing you did not value, someone else wished it's theirs,
That situation you hurriedly want to get out of, someone else wished they are in it
That place you wish to get out of, someone else wished they are there
That food you rejected, someone else wished they can have it for three square meal.
Whenever you see the breaking of the day, just utter the word "THANK YOU LORD"
Have a blessed Sunday and make sure you go to church (Christians) or Asalatu (Muslims). ciao
