Many a time the street is noisy. Everywhere you turn something tries to call for your attention in attempt to detour you from your direction of travel. It could be opinions, fears, suggestions, accusations, or misconceptions. You must plug your ears with a filter to choose what to absorb and what to discard.
Freedom is the liberty from the opinions and prejudices of others. Someone once said, if you stop and throw stones at every dog that barks at you, you may never get to your destination.
When the envious shoot uncomplimentary words, stay focused.
When the ignorant are confused by your actions, stay focused.
When temporary setbacks try to hedge you in, stay focused.
Focus will help you maximize your creativity and attain great milestones.
