Hello! I only see 6 sentences in this paragraph, I'm proceeding to check the grammar, I'll try not to modificate it much.

Having a high school diploma can be important for your future, because college admission counselors and potential employers usually won't consider you unless you have one. It is important I get high school diploma so I can accomplish my goals. I want to be able to show my family that it doesn’t matter when you achieve your goal, as long as you have the perseverance to complete it. It’s worth it to get a high school diploma to show employers self-discipline. By doing my work towards the diploma, I'll lay the foundations to succeed in a college degree or training program. I will work until I receive my diploma and graduate.

Here goes my correction:
