There is a saying that goes:
Winners never quit, quitters never win.
When you set a goal for yourself, you are setting it with the intent of actually achieving it eventually, if you giveup on those goals, why did you ever set them... Why did you waste your time and effort to set a goal that you ultimately knew you were gonna give up on.
As harsh as it is, this is the sad truth, we all set goals for ourselves, whether it be because we want to raise our self esteem or whether it be for our growth. Setting a goal is obviously a good thing, but not if you do not intend to achieve it...
