Find a person that you know personally that might be at where you want to be, and use that as motivation. I've always had like a silent competition with somebody that was where I wanted to get to. My cousin played pro basketball overseas, so I wanted to beat him when we hooped. One of my older Brothers got locked up and sent to boot camp, and he said they'd have arms wrestling competitions and he was unbeatable, so I wanted to beat him in at arm wrestling. I beat them both, and got better/stronger in the process.
