Congratulations on a job well done. You deserve your success.
You miss one hundred percent of the shots that you don't take. A fear of failing or getting something wrong will not help you to improve or grow. If you don't try, you may never improve or succeed. Life isn't about being perfect, it's about challenging yourself to grow through trial, error, research and persistence.
Online resume sites where you post information about yourself are not as important to hiring managers or recruiters as you might think. Don't put all of your eggs in the online resume basket.
