I am a firm believer in the quote "Do something you love and you'll never work a day in your life."
I think following your passion is one of the most important things you can do for yourself. You should find whatever it is, that your passionate about and work hard every day to achieve that goal. I'm not saying it will come easy. You might be afraid to fail, but do not give up.
I'm a victim of this, but I am here to tell you that fear is in your head. There will be obstacles and steps to take before getting exactly where you want to be. It will only make you stronger. What I have learned, is that people will always doubt you. I have been told I am not the right fit for what I am trying to pursue. That there is a slim chance that I will have the job I dream of having. You know what I said?
You don't have to tell these people how good you are, you just show them. There will be people who say your dreams are not realistic. You have to use these people as motivation. Prove them wrong. Do not quit, ever. I promise, if you give 100%, you will not fail. In the end, you will be so satisfied with yourself, and more importantly, you will be so happy to be living your dream every single day.
When you have accomplished every goal you have for yourself, you have succeeded! And when you are able to wake up on a Monday, excited to be going to work, you are officially a boss babe!
