It's a long time saying that goes winners never quit and quitters never win. I totally agree with that statement because I've been through some tough times while trying to reach a goal. I never would've accomplished anything in life if I threw in the towel.
I remember when I first started internet marketing. I was a complete novice going through one sales page to the next. I bought this and I bought that, only to leave me with an empty wallet. Information overload had taken a hold on me and I thought that my goal was going to be further than I can reach. Because of my passion for internet marketing, I didn't quit. I finally made my first sale with something that worked and it inspired me to keep on going.
So whatever your goal is, make sure it's something that you want really bad. Once the going gets tough, never ever give up because success could be right around the corner.
