Be strong now, because things will get better. It might be stormy now, but it can't rain forever.
Dreams are a way for your subconscious to release any pent up worries or frustrations, and for you to visualize your goals and objectives in life. Everyone dreams, even if these subconscious movies are not remembered when you wake up. Dreams are different from nightmares because dreams are typically pleasant while nightmares are terrifying or disturbing in some way.
Be strong now, because things will get better. It might be stormy now, but it can't rain forever.
If you don't sacrifice for what you want, what you want becomes the sacrifice.
Challenges are what make life interesting and overcoming them is what makes life meaningful.
