Sometimes we do something without thinking carefully and deeply about it and only after a few days, we see the unwanted results of what we had done. There is a Turkish proverb, which says that the devil takes a hand in what is done in haste. Here are some expressions that I have collected, which will easily remind us in the periods of difficulty that haste will make waste.
"Hold your horses" or "hold the horses" is an idiom, which has originated in the U.S.A in the 19th century. This idiom literally means to keep your horse or horses still. However, "hold your horses" is generally used to tell someone to stay calm, be patient, or not get very excited.
"Keep your shirt on" is another phrase with the same use and meaning. Unsurprisingly, people react to a fight differently. Some of them rip their shirts off to show that they are ready to fight. Instead, the other group of people avoids fighting and shows this by keeping their shirts on. Perhaps they are afraid of losing their shirts.
"Hold everything" can be a good advice for those who are in a hurry. It means hold it, stop, or wait. Remember, this phrase is usually used in imperative sentences. Like, "hold everything, we must give Ben a call before leaving the house."
"Cool your jets" apparently comes from aviation. People use it to say, "Calm down", "relax", and "step away from situations, which are likely to cause arguments".
