Don't weigh the pros and the cons. Don't keep telling yourself you're a procrastinator. Just do it. Then your procrastination will be a thing of the past. If you think I'm joking about this, or taking it lightly, you're missing the point.
Procrastination is one of the greatest obstacles to success.
And it's the easiest to overcome. All you have to do is to take action. Any action, no matter how trivial, will do the trick. In fact, the easier you make it on yourself to take action, the easier you make it on yourself to beat procrastination. If you are so intimidated by a task that you just can't face it, break the task into smaller steps.
