During my review for the medical boards, I gained 101 pounds in four months and promised to exercise when all of this was over. I successfully passed the medical boards and _ . One morning, I woke up and decided to go to a park to start working out. I got out of bed, washed my face, brushed my teeth and put on my sports shoes. Then I headed for the park. While going there, I decided to set a goal for myself, that, I had to finish 10 rounds before I went home. Upon reaching the park, I joined the people in walking around the park. I was enjoying every step, breathing in fresh air, appreciating the green grass and looking at the dried leaves falling from the trees while listening to my iPod. On my 5th round, I felt tired, hungry and thirsty. I thought of giving it up, going home and sleeping again. As the idea battled in my mind, I was reminded about the goal I had set just a while ago. I kept on walking and as I looked around, I saw myself in the midst of men and women much older than me who continued to move on. Some even suffered from a stroke  that had difficulty walking, some took on small steps with a cane on hand and some took on pauses before they continued their walk but still they kept on walking. Suddenly I realized that each of us has set our own goals in our lives, such as reaching a dream, building up a career, correcting a past mistake or starting a business. The process won't be easy. We may encounter  a lot of difficulties and obstacles that may push us to just give up. Amazed by the men and women whom I walked with that morning, I finished my goal in the end. Let us be inspired with the people around us who experience the same or even a greater amount of difficulty but still don't give up and continue until they reach their goals and now are savoring  their success.

he didn't want to continue walking he found it easy to keep his promise he was enjoying walking in the park he was too tired to keep up with others
