It's a good idea to reexamine your toughest goal today: because it is probably too unrealistic for you to reach, at least just yet. Frustration is not a good motivator right now, so ratchet things back and give yourself a more reasonable expectation of what can happen in your given time frame. You deserve to feel like a success, not like someone who can never quite reach that brass ring. Adjust your sights and be more reasonable. The win will feel just as good.
