For me this hard work began when my parents were no longer able to afford my school fees making me drop out for a while. As much as I was devastated, I told myself I was going to gather the right skills and experience, so much so that I will have an edge over those with certification.
That's commendable! There are many people who get stuck in the absence of opportunities and don't open their minds to creating new ones. You were very determined and in the end you achieved your goal, congratulations!
