I think if you want to become a great football player, professional, you must give all the time one hundred percent, you must work hard - to be lucky is a good thing - but if you work hard and you give everything you will have great success.
If you have only one passion in life - football - and you pursue it to the exclusion of everything else, it becomes very dangerous. When you stop doing this activity it is as though you are dying. The death of that activity is a death in itself.
You are today where your thoughts have brought you; you will be tomorrow where your thoughts take you.
