Have you ever noticed that so often, when you're thiiiissss close to reaching a goal, an obstacle pops up that threatens to defeat you?
It's happened to me so often that now I simply plan for the obstacle.
I don't know what it'll be but I know it'll be something!
Since I can't plan for what the challenge will be I prepare by telling myself to not let whatever it is get me down or, in some cases, slow me down.
Depending on which strategy I think will work I either double my efforts, pick up the pace, or back off a little, relax, and let things work themselves out.
If you're pumping away on a project how will you react if an obstacle pops up?
