During the secondary school I had not studied so much as I had not enough work pressure. I knew my marks were not important for my professional future so I gave priority to another things like my football team or friends.
When I started bachillerato, I decided I had to change. I started that year doing all my homeworks, studying hard and missing many training and weekend time due to my studies. Since that moment, I have completely changed and I am so different with respect to two years before.
In conclusion, the start of bachillerato was a great turning point for me as it has defined what I am as of today.
