If you make 1000 origami cranes is it true that you will get a wish or good luck. This is based on a Japanese myth
It's like asking: If you make a wish on a shooting star, will it come true? Although both are nice gestures, no it will not come true. Origami cranes are simply pieces of paper that are folded to resemble birds; no matter how many you make, they will not take on supernatural abilities such as wish-granting.
That depends on your wish. If your wish is to have 1000 origami cranes or your wish is that you become really good in folding origami cranes I would think it will come true. But maybe you could also wish for a smile from every stranger you give an origami crane to as a present, you might not even have to wait until you've made 1000.
