If You allow people to Define You, You have indirectly allowed them to subconsciously Confine you. I dare say that any Classification whatsoever is a Limitation!
Familiarity is when familiar people from the past and even those in the present Think they can somehow determine what you can or cannot do in the future based on the actions and in-actions of the Past. But no one Knows what you could achieve or become in the future. Except God!
It is most dangerous when you tell your future dreams to Familiar People. To be Precise, Familiar people are Peers, Parents, or Partners, who cannot overlook the weakness of your past, and therefore cannot perceive the possibility of a better and different Future. Familiar people are always at familiar places; family house, old neighbourhood, Mother churches, Old School Reunion, Alumni meetings.
The family is however the biggest culprit.
Family; No wonder familiarity is derived from the word family. Family is often good for everything except the achievement of a Vision. The biggest deception of Family members is that they believe they know you more than you know yourself. But since Potential is always hidden, this mindset of the family often becomes a great threat to its manifestation. That is why God had to take Joseph from his family; the family sometimes becomes poisonous to your future because they still interpret your future from your past.
Harland David Sander, started his famous Kentucky Fried Chicken in his
60's, I guess most familiar friends had written him off. What a person has done in the past should not necessarily correlate to what He can do in the Future. Remember! Every Dream has Only One Believer initially, Yourself.
Disclaimer; Old friends and families are the best, but when they don't appreciate your dreams or potentials you have, forgive them, because they might be too focused on your Past that they cannot see Your Bright Future.
