You can be whatever you want. You can do whatever you want with your life. Can you think of it? Then it can be done.
Many innovators came from "humble beginnings". Take for example a young Bill Grates, building Microsport brand computers in a disused septic tank in his parents' backyard. Do you think he thought anything would become of his life or his brand as he was pacing back and forth in ankle-deep waste sludge, loath to see the sunlight? The answer is, no. He probably envisioned a slow death in an atmosphere of significant odor. And look at him now! Well, he was doing well up until his untimely, recent death.
Also do you think the inventor of Tetris™ ever thought his idea for a video game would one day be adopted into a multi-platform empire? That its popularity would one day reach its apex, its zenith, with a guy who lives in Queens (me) playing the Electronic Arts™ licensed version of Tetris™on his computer phone while riding the M train? If you had told young Alexei Serganov (inventor of Tetris™) about this eventual possibility, he would have cursed at you, because he was rude and had Tourette's syndrome (not sure if there's a different word for it in Russian, or if the guy was even Russian). He just knew that he had a bunch of crazy-shaped blocks in his head and wouldn't it be cool if there were a game where all the blocks fell down one by one and you had to fit them into place. He'd been fitting those blocks together his whole LIFE, he just never knew it (metaphor).
Lastly, how do you think "Gentleman" Che Guevara would have felt if he knew his legend would resonate throughout history? One of the finest boxers in Spain, he was known for his good manners and clean-shaven appearance. But one day he would come up against Kid Fidel (Castro) in one of the most controversial bouts in the history of sport. Hotly debated even to this day, the "Slammer In Havana" as the fight was known, ended in confusion when the two fighters touched gloves, then touched gloves again, then continued touching gloves for over 7 hours as the referee pretended that a road flare was a cigar he was smoking, and the undulating, amorphous crowd burst into flame and fused into a solid mass of flesh.
