Yes you right, mate.
"The journey of thousands of miles begins with one step." - Lao Tzu
Your life is like a long journey for a human. Life has the purpose that you want. Achieving these goals must be accompanied by effort or hard work. Sometimes the effort required requires that you sacrifice a number of things. At first glance it does look heavy, but you will get used to live it. Only one initial step to achieve your dreams: start moving from your comfort zone and work for the things you dream of.
This is what scares many away from pursuing their dreams. Thought of failing due the size of what lies ahead is the number one undoing of man.
Do not worry about what seems impossible, worry about the hooks that lay waiting for you to cling to.
Stay Awesome!
