Proverb: If you do not change direction...

[Mugi]

Am checking a translation from English into Japanese and have come across the following line:

... I used a Chinese proverb, "If you do not change direction you will end up where you are going."

Does anyone know if this is an "actual" Chinese proverb, and if so what the original Chinese is?

Thanks in advance!

It sounds like this: 穷则变，变则通.

穷：end

变：change

通：pass through

Change the direction if you meet with an end, so that you can pass through.

Thanks!

Thanks. Unfortunately the English means the opposite (In order to reach your desination, you need to keep travelling in the same direction: Think George Bush: Stay the course).

I can only come up with 只要有恆心，鐵棒/柱磨成針.
