Focus on one thing until successful is good advice. To avoid overwhelm. When busy.
With a poor track record for knocking things over. Making your next step more obvious, more attractive, easier to do, and more satisfying makes a lot of sense.
This is why in age-group football aiming at two goals maybe better than one.
The pitch has 4 goals. It’s obvious.
The chances of success are higher. It’s attractive.
There are more opportunities for every player to shoot. It’s easier.
Kids love to score goals. It’s satisfying.
You can’t take a second step unless the first one is successful. Crawl. Walk. Run.
