Most scientific breakthroughs don't come from a "Eureka!" moment. Most come after gradual progress that leads to that point. Nobody (except that first Greek, maybe) runs a marathon the first day start running. Hollywood is littered with actors who became an "overnight success" only after years of grinding away in obscurity.
Progress can take time. The temptation is to quit before you see any results. Whether it's getting fit, finishing your degree, or becoming the best at what you do, every day is an opportunity to move forward.
Keep it up.
