What does it mean to do the same thing repeately but expecting a different outcome?

Some say, the definition of insanity is doing the same thing but expecting a different result. When you use the same thought process, same approach, maybe same system over and over again and still getting the same result, it's time to change the above mentioned. Kind of like if you were to get in your car....and make car noises but the car doesn't start. You really want the car to start, and day after day you go and sit in your car and make car noises. Stop and think, how else will this car start. Hmmmm. Maybe use the key, then the car will start. Another saying, there isn't one way to skin a cat....ouch...I know sounds terrible but basically the same idea. There are several methods you just have to keeping trying until you get your result you want. IF? You have tried everything including what everyone else even suggests then maybe it's time to find a new goal or different outcome. Be flexible because life isn't!
