You've Come Further Than You Think

In Adam Grant's book, Originals he puts forth one of the best courses to take when you have doubts on the road toward achieving a goal:

"When our commitment is wavering, the best way to stay on track is to consider the progress we've already made. As we recognize what we've invested and attained, it seems like a waste to give up, and our confidence and commitment surge."

In other words, we need to set-up small "wins." When you track your progress, your doubts often turn into a sense of enthusiasm. He goes on to say:

"Once commitment is fortified, instead of glancing in the rearview mirror, it's better to look forward by highlighting the work left to be done. When we're determined to reach an objective, it's the gap between where we are and where we aspire to be that lights a fire under us."

Remember to take inventory of what you've already accomplished. It's likely more than you think and enough to persuade you to continue on your path.
