Perseverance is that "stick-to-it-ness" that is required to keep going long after your motivation to do something has waned.
It is hard to persevere in the face of difficulty. We want to give up, we want to quit, but somehow we continue to strive, to struggle, to push through.
For me, perseverance is the key to success. Without it, I will just make excuse after excuse about why I don't want to or shouldn't or whatever!
To do what we know we must do take perseverance. Motivation might add a helping hand, but without perseverance, forget about it!
Perseverance, not excuses, will get you to your goal!
