please correct this

I am currently attending college, in my senior year, about to graduate within a few months. I have visited the Guidance Counselor's Offfice and talked with her about possible steps to take after college. She gave me some good advice and I am going to follow up on some of her advice. Right now, I am thinking, or day dreaming for that matter, about my years ahead: If I am lucky, I will be able to find a job in a Fortune 10 company that possibly has a subsidiary here in XXX. and after a few years of hard work and some luck, I will possbly be able to move up in rank to a supervisor in my department. A few years after in a supervisory position, I will possibly be able to be a vice-president of some operation and move up to be president after that. From an entry-level position to being president, I figure, will likely to take about fifteen years with more-than-I-can-imagine luck and hard work. After five or so more years as president, I will also probably be able to retire with a sizable pension and retirement benefits; and I will be able to rent or buy a house near a beach, rent a boat, and enjoy the rest of my life looking at sunrises and sunsets, in the beach-front terrace, sipping cool lemonades in summer and hot chocolate in winter. Until then, I think I have to study and work -- and pray -- hard.
