True happiness can only be obtained by giving back to one's local society. More precisely: LIFE'S PRINCIPLE AXIOM IS THAT YOUR INSTINCT IS TO PERPETUATE YOURSELF----TO BE. PERPETUATION INCLUDES, IN ADDITION TO YOUR FINITE LIFE, THE EXTENSION OF YOUR MEMORY AND INFLUENCE AFTER YOUR DEATH. A HERO IS PERPETUATED BY HIS GLORIFICATION, OR MORE PROFOUNDLY, THE PRESERVATION OF HIS SOCIETY.

Al principio viviré de alquiler, pero también espero comprar una vivienda. Además, me interesa la enseñanza de matemáticas, así que si saben de alguna vacante, por favor, avísenme. Gracias.
