When all the goals are chosen for you, it does not matter if you were over-protected or not. You cannot build true self esteem and confidence if you don't succeed and/or fail at a dream of your choice. There is no point learning to drive a car if you do not know where you want to go, to earn money if you don't know what you want to buy, and to get into a career if you have no sense of purpose.
Videogames are addictive not only because they are fun, they provide you with a goal and 'achievements'. In my humble opinion, sex for the sake of sex (real or porn), promotions for the sake of promotions or else are all caused by the same emotional male problem ; the inability to feel emotions and learn from them what is truly important for yourself. The % of young men in the labour force is just a symptom of that.
