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.
