One of my mentors told me a story from his high school days.
There was a kid who always got into fights every Friday. The kid was small, so every time he fought, he got beaten up.
But here's the thing: he would get back the next Friday, only to get beaten up again.
The next weekend, the same thing. Until one day, everyone decided to stop fighting this wacko because, man, he didn't quit.
The moral of the story is that no matter how beaten up you get if you keep coming back and not quitting, you win.
Many people give up before they even try. Don't let that happen to you.
Take a look at the things you're doing and choose the one you're most passionate about. Then ask yourself, "If I keep showing up and working on this for the next 365 days, even when I get tired and do only the most basic part, what will the result be?"
If it's something you're truly passionate about, commit to doing the most basic part for the next 10 years without giving up.
Imagine what the result will be.
Instead of telling yourself all the excuses, just tell yourself, "I will not quit. I will show up and be there." That's it.
Remember that you can only lose if you quit.
