If you want to do anything well, practicing it again and again is definitely a way to achieve peak performance and excellence. Break the bigger task into smaller tasks, focus on one smaller task at a time and mentally repeat yourself doing that task. You can also physically go through the process of doing that task. When you actually get to do that task, it becomes so easy and you can do it excellently in a very short period of time.
See the big picture, break it into chunks, mentally repeat a chunk.
Thats how the professional sports teams execute the plays perfectly everytime. They repeat the same steps over and over to prepare for the big game. Thats how the olympic players prepare as well. Four or more years of preparation for a four minute attempt for the gold.
We are creatures of habit. Excellence is a habit, but don’t fall for the perfectionist trap!
“We are what we repeatedly do. Excellence, then, is not an act, but a habit.” – Aristotle
