You ARE strong enough to live it! Don't let what others say get you down! You were made to make a difference in others, not to impress people! You ARE strong! Live your life to the fullest and don't let anyone stop you from pursuing your dream!
"If the plan doesn't work, change the plan but never the goal." Sometimes I do this in the midst of a lesson plan! The fact that my day can be so well-planned and then so unpredictable is one of may favorite parts of the job.
