Too many players want to have six superstars at their practice session, and will call and ask who is going to be there and if the right people are not going, they skip practice for the day or they show up and goof around for the day.
Instead of flying in superstars, by leading from example, you can build those around you up, you can make them better, and you can build your own environment to where it is super strong. This is often spoken about with Michael Jordan and how he pushed his team mates to work harder than ever before.
First you need to earn the respect of those younger or less talented than you, then you need to show them through example what dedication, focus at out-performance looks like. Help them stay motivated, and you will be amazed at how hard people try when they practice with you.
