Following four decades of involvement in nearly all aspects of direction, by identifying, qualifying, training, developing and consulting leaders, to functioning, being a leader, for several associations (large and small), I’ve often been asked, what I think, to be, even the most significant factor of principle, of leading efficiently. I have discovered, and learned, while it is likely to train some one, and furnish them with the needed and necessary abilities, to proceed, sensibly, an individual must begin the procedure, having a certain kind of mindset, and also attitude. In case this must be summed – up, only, and essentially, it would be, an individual has to be directed by the core principle, to do, what’s perfect! Keeping that in mind, this guide will try and briefly examine, consider, and talk, together with the mnemonic strategy, why understanding human nature. And/ or that which causes us do, what we do, is crucial and important. It’s important to proceed in a righteous fashion, without having to be self – righteous! Just how would you understand what is relevant, until/ unless he pays keen attention, to the advantages and weaknesses, and the positives, as well as negatives? Leading must focus on being attentive to needs, aims, priorities, and the mission of this group! A leader is responsible for effective leadership preparation, and seeking tactical and action plans, together with sustainability, and understanding ramifications, as core components.
