If Winter comes, can Spring be far behind?

"If Winter comes, can Spring be far behind?" said by Percy Bysshe Shelley, which encourage people got in quandary.

For a long time I was depressed by studying English. Because my careless and inadvisability, I caught in a big trouble in studying process. I complained, regretted, and went downhill. For some reason I told myself I can not always force into regret showing sympathy to myself instead of bestirring. I had to pass it so that I make hard effort on studying 10 times harder than before with the hope to redeem the mistake I have made. Our capacity to cope successfully with life's challenges far outstrips our capacity to feel nervousness

Holding onto regret is like dragging the weight of the past with us everywhere we go. It drains our energy, leaving less available for life in the present because we are constantly feeding an old issue. When you take steps to eliminate the fear, you can more fully enjoy the excitement. Though you may find it difficult to avoid getting worked up, your awareness of the forces acting on your feelings will help you return to your center

We should live in this world when we love it.
