Sometimes when you are putting more into something that it is worth or ever will be worth, it's time to cut your losses. Whether it's putting off buying a new car, or maybe something else, you need to determine when to cut your losses. Basically, when the juice isn't worth the sqeeze, like a former mentor of mine, CLB used to say. So make sure you understand when that time is and step into action. After all, knowing when to cut your losses is the right thing to do and it models the way for others.
