How do I buy bitcoin on low funds

I stopped drinking booze by doing this I slowed the aging of my body and improved my quality of life. I stopped buying cigars and cigarettes by doing this I slowed my aging curve and improved my health and I smell better as well. I stopped going out Friday nights and or Saturday nights and stayed home and cooked healthy foods and educated myself. I started thinking about any purchase I made asking myself do I really need this how will it improve my life. I stopped buying over priced sneakers all the time. I stopped buying full price designer cloths and looked for deals, I stopped jumping into trendy fads, I stopped paying for cable tv and I upgraded my internet to stream tv instead. I started changing my mindset. I began to believing that spending everything I earn today is nothing more then a poor man's mind set and that saving my energy in bitcoin and other stores of value is a rich man's mind set. It is not what you make it is what you spend. Bitcoin is the way we will all change the world. It is not our purpose to change the world it is our desire to create a better, stronger and harder system where we can save our energy and our time to use at a later time. A system where people are not forced into it a system where one volunteers to join because it is far superior to be free.
