Are you a procrastinator?
I have to say yes to this question unfortunately but I have found ways to over come it. The Putt it off Blog has 28 ways in which you can overcome it yourself.
I overcame it by setting very specific goals with specific targets and sticking to them. I also have a very competitive spirit so I use that to be a motivating factor.
Take a look at some of the suggestions and see what will work for you. Just because it works for person A does not mean it will work for person B, so you need to find your own path to overcoming this vise.
Here is another area where a mentor can help you. Seek someone that can watch over you and motivate you to overcome the problem. Don't let procrastination harm your potential for success, overcome the problem and be stronger for it.
