After more than four decades of participation in the majority of aspects of leadership, from identifying, qualifying, training, consulting and developing leaders, to functioning, like a pioneer, for several organizations (large and small), I’ve often been asked, what I believe, to be, the most significant consideration of rule, of contributing effortlessly. I’ve detected, and learned, whether it is possible to teach someone, and supply them with the necessary and essential abilities, to proceed, wisely, one must start the process, with a certain kind of mindset, and attitude. In case that had to be summed – up, simply, and essentially, it would be, an individual has to be guided by the heart principle, to do, what’s appropriate!

And/ or that which causes us do, what we do, is important and relevant. Righteous; relevant; reactive; responsible; effects: It’s important to move, at a righteous manner, without having to be self – righteous! How would one know what’s relevant, until/ unless he pays keen attention, to both the strengths and weaknesses, and the positives, as well as negatives? Leading needs to concentrate on being attentive to demands, goals, priorities, and the mission of the group! A pioneer is accountable for effective leadership preparation, and hunting tactical and action plans, with sustainability, and understanding consequences, as core components.
