It's a treadmill. The belt runs at 10 miles an hour. It's fast. When you get onto the belt, you have 2 priorities: (1) Don't fall, and (2) Adapt.
Any skill or company is like a treadmill. To excel at the skill or in the company, you need to balance these 2 priorities, together. That's the key - together.
If you only try to not fall at first, you will never adapt. When the speed changes, you will fall.
If you only try to adapt at first, you will fall nonetheless.
To make progress, then, it's important to learn the basics and try the advanced stuff. Stay grounded, but aim for the sky.
That's the treadmill. That's most things. That's life.
