Some lazy, some efficient... everyone handles summer vacation in their own way. Where good things happen, so shall bad things as well...
I suppose it was the result 
of all the effort I put in.
Probablemente es el fruto de mi esfuerzo...
Seguramente es el fruto de mi esfuerzo...
Ça doit être le fruit
 de mes efforts…
Deve ser o fruto de todo o meu empenho.
