I use to be concerned about that when I was at your age, but now, after having to face major tragedies in my life I learned that the poet was right when he said that "All is worthwhile if the soul is not small." (Fernando Pessoa). I never get tired of learning, even if what is shown as new smells like dejá-vu. Learning is something that rewards you not only when you achieve the goal, but in the process of achieving it. I tried the management path and I was good at it, but I really enjoy programming better, so I get programming gigs as much as possible. One thing in my favor is that I don't have any aspirations of being rich, stability and alike. This open my choices of jobs.
