Al igual que con el cuerpo humano, cuando se daña y regenera, lo hace con mayor fuerza y vigor del que tuvo en tiempos pasados, para así evitar volver a ser dañado de nuevo. Si cometes un error, no lo llores, enmiéndalo y prométete a ti mismo que jamás volverás a cometerlo, con todas tus fuerzas, empeño y confianza.

Nobody was never able to create something extremely good, useful or incredibly beautiful without having made mistakes of all types before. A mistake, is not an end, is another chance to make something better, and baring that mistake in mind, making effort, don't do it again for a second time, learn from it, try the best to reach your goal, whatever you have been waiting for.
Like human's body, when it is hurted and regenerated, it makes it with much more strength and power, just like ancient times, in order to avoid hurt again. If you make a mistakes, don't cry for it, repair and promise yourself that you'll never make it again with all your strength, will and trust.
