You don’t have to rush. Your goals will be there tomorrow and the day after tomorrow. (And if you’re afraid they won’t, you should probably redefine them.)
Yes, it would be ideal if you could accomplish what you set out to accomplish sooner, with less effort. But not at the cost of your own mental health.
If you’re sleep-deprived, you won’t be productive. If you’re stressed and torn into a hundred different directions, you won’t be focused. If you’re in a rush to achieve something, you might miss essential lessons along the way.
It’s a marathon, not a sprint. Better to get there in one piece than fast.
