Life is full of change and having a goal helps you focus on learning and gets you working towards whatever you want to achieve.
You don't need to wait for others to accept you. Only you need to accept who you are and treat yourself well. Acknowledge you are important and be your own cheerleader.
You may be scared, but you need to try new things and encourage yourself to change. Success does not come to us if we do not step out of our comfort zone. You must branch out into the unknown to learn and achieve new goals.
