Watch children learn new skills. They learn by imitating and then they try to use it again and again. Watch a kid who has just learnt cycling. Kids always improvise and try to achieve perfection.
Learning leadership skills as an adult is similar. The only difference is that as a professional, those around you may not give you direct feedback. But you will see signs if you do something wrong. Reading those signs needs extra sensitivity and reflection.
Learning Leadership web based programs at http://buff.ly/P2mKIj and the Lead to Regenerate program book http://buff.ly/P1TzFE give you things to learn and ways to try out what you learn in real life work.
Start on them soon!
