Question

I will be able to work towards getting the skill I need for the career I want. This will give me better confidence, that I no longer have to settle for jobs I am not suited for. Knowing that I can make my dreams become a reality . This will help me to better things for me and my family. By providing them with the guidance for a better future, financially and by my own personal example. Showing even if you failed the first time, always keep trying like I did by getting my high school diploma.
