One meets people in life but those who inspire, guide & encourage without any expectations play a significant role and shape one’s life. Therefore surround yourself with people who add value, bring out the best in you and celebrate your success.  It is normal to disagree over some issue but important to handle disagreements in a way you do not alienate the trust worthy. Healthy criticism and honest appreciation must be welcome but be aware of the extremities of either or both of these factors.
