First impressions are the filters through which every other thing you do is by default seen and interpreted.
What impressions do people have of you as a leader?
All other transactions, be it of a conversation, a partnership, a high valued relationship or a financial commitment, all of these and many more will be decided upon by the filter of what impression you create at first thought and first sight.
To enhance the first impression people should have of you, begin by being intentional about developing and living by the right values, keep to the right goals, uphold personal high standards and represent what you stand for in all obvious ways.
These are not rules in stone but guidelines to help you navigate daily human interaction and create the right impression that outlasts your presence and rewards your effort for long term benefits.
