Elimination of Desire

I understand the concept of eliminating my desires because they arise through causes and conditions that can be understood and changed. But how can I actually do that? What does it even mean to live without desires? How would my life look and feel without them? I am definitely hesitant and a bit frightened by the idea of living without desires. Is this what people refer to as a slave mentality? Would I lose interest in everything I consider necessary for a good life? What about my hopes and dreams? These thoughts fill me with fear.
