Hockey superstar Wayne Gretsky said "You miss 100% of the shots you never take." Unlike those who sit on the sidelines of life, I least I gave it my best shot. I need to push forward from this setback and keep aiming high. If I do not get accepted into the Bachelor of Health Science: Health and Society does not make me a failure. Focusing on my plan "B" would be my main focus because there is more than one way to get to my goal. My plan "B" is to get into the University of Calgary's Bachelor of Science: Environmental Science program. At home, when my brothers or parent carelessly rip a large piece of tissue paper to clear a small mess, throws a recyclable can into the garbage they know they better start hiding. My lecture to them starts from why they should try to change their bad habitats to talking about all the environmental problems we are having today due to waste. By the time I am done with my lecture they get the point but for me I feel like it my job to make sure the recyclable gets to the recycle bin and the tissue paper is replaced with washable towel. Even though I am still in the process of reforming my family I want to be the catalyst that will push forward the environmental movement of Canada and someday the entire world. The environmental science program focuses on understanding environmental issues that is facing society today. Knowing this, I am confident I will thrive academically and socially in the environmental program.

Can someone help me edit it and is it good enough? and how can I make it better
