The problem about progress is that you rarely see it.
Or feel it.
The problem about mistakes and failure is that you always see them.
Or feel them.
That's why it's so difficult to keep pushing.
Because it'll always feel like you're either standing still or falling behind...
So how do you know whether you're making any progress at all?
The only thing that's for sure is that once you stop putting one foot in front of the other you'll stop making progress.
So as long as you keep putting one foot in front of the other and keep walking, you'll keep making progress.
It's as simple as that.
But not easy...
