A toaster makes a stale bread looks fresh but it does not really make it fresh.
People, situations and things that look similar are not always the same.
Your positive mentality can easily paint a nice picture about you and your world but it does not perfect you and your world.
Based on our limited knowledge and uninformed judgment, we can easily adjudged ourselves as best and flawless.
Be critical and unbiased in your observation in order not form a nice but a false image about yourself and others.
Remain in the love and peace of God.
