Never give up hope. No matter how hard your life becomes -- no matter how impossible your dreams and goals may seem -- just know, it's possible. Say to yourself, even amid a depressed and hopeless mood, "It's possible." "It's possible if I believe in myself." "It's possible if I just work a little harder." "It's possible if I'm just a little more patient." Never let go of your dreams and goals because that is what defines you as a person; that is what gives you reason and motivation to continue living -- and by living I don't mean just "existing" -- I mean living each day meaningfully and productively.
Just know, the process to true success and happiness is never easy, is never quick. There are countless obstacles and distractions that threaten to bring you down and keep you down. But you don't have to succumb to them. Keep the big picture always at least in the back of your mind. No matter what happens, always try to remain calm and objective and focused -- focused on the right thoughts and the right actions that will one day lead to the success and happiness you've always envisioned and desperately wanted.
Life is never easy for anyone. And the quest to the fulfillment of our goals and dreams is even less easy. But never give up hope. Never stop trying. It is possible. In fact, with the right attitude and work ethic, it's just a matter of time, it's just right around the corner.
