Great quality and FREE ACI Training!

Many people whom I’ve mentored have advanced degrees and certifications – like MSc, CCIE, even Phd., and other certifications, who are far more qualified than I am – and they are the ones reaching out for guidance!
What I’ve learned from this is that those are not afraid of asking for help, and don’t let their ego or nervousness or hesitation or riskiness or whatever else may be holding them back get in the way, end up being most successful.
