How do I rid myself of the insecurities that are preventing me from becoming confident and outgoing?

At least take 10 minutes every day,preferably in the morning to remind yourself that you deserve better,and that you are your own best friend first. Care about you,and this will reflect in your attitude through out the day. Remember the things that are special about yourself because when you deny them,you wipe them from your spirit as well your life. You have a good and positive start because you as well know your strong points,put them out there when ever possible and enoy the fruits of the rewards they bring,as that will aspire you further and bring more inspiration as well. That being said not a thing wrong with being shy either, those who are loud,pushy and boisterous have problems all their own,as they are viewed as obnoxious by many,so just be glad you do not have those problems..
