If It Ain't Broke, Don't 'Change' It

To borrow a popular say, if it ain't broke, don't fix it. Normally this apply to a problem or things where its not broken, don't do anything on it.

For a thrifty people, we probably will not change a usable thing if its still running. We will continue to bear with it regardless how many new models or how good the new things is. Plainly because,we we believe if it ain't broke don't change it. But sometimes I guess we may change an old equipment just because is too old, become a liability, we require better functions or simply we can afford to.

But of course nowadays, many people simply change for new just to keep up with the trend or maybe they really have the money.

So what's your reason to change something? :P
