Do not fear being yourself.
The person that you are is unique and entirely worthy of the best in life. Only you hold the ultimate power to shape your life into the form that you want to grow from.
Step up and be a leader.
If you bear witness to someone being bullied or an event you know is in need of guidance or assistance, do not be a bystander. Take action. Not only will stepping up boost your confidence but it will also greatly impact the person that you helped.
Contrary to popular belief, everyone makes mistakes (even teachers. My apologies, Mrs. Hebert!). Do not let the fear of looking wrong prevent you from truly learning material in the classroom or outside of it. The ability to question is human nature, it allows us to formulate individual thoughts and reason with ideas.
Take risks and do not dread fear.
You can never learn something new if you don't try it. Perhaps the class or speech you have regretted signing up for will benefit you twice over, more than anything else ever could. Without rejection, one would never experience the euphoria of acceptance. Without searing pain, one could never truly grasp the sanctity of contentment.
With this said, it is up to you to determine how to use these tidbits of guidance. I wish you all the best in your future endeavors.
Dare to be different!
