I don't know where I got this, but it's one of the most important things that I learned in my life (and I usually really, really hate shitty inspirational quotes): "80% of sucess is showing up".
Keep going, do the work, be there. Maybe you also will try to give your best today, but it's more important to just be there.
If you can keep this every day up for a long time, then talent, luck, inspiration, knowing the right people, money, fame, etc. will suddenly all become more and more irrelevant. You'll realize that these were just excuses that you used for your own failures ("If I knew the right people..."; "If I just had more money..." etc.)
Constant work is is the most important thing in every occuptation.
