blind can do powerpoint slides too

Today I had presented my slides the blind way. I use the help of JAWS to present. Instead of using my vision to read what is on the slides, the software helps me to read line by line. The problem is, I put the reading speed too fast, kinda like mumbling my way through. I wish I have learnt it when i was in uni, then I won't have to struggle so much! Nevertheless, I of course got help from a person that has no visual problem to help me check my slides. (and you know who you are).
Sometimes my mom ask me, why I have to go so hard against myself by working since I'm already nearly blind. Many people think blind people are those that has bad past karma and are paying for their bad doing in past lives. Why can't they see is as a challenge from God to teach us lessons in life? Of course its not easy being a visually impaired and deteriorating stage, waiting for the day you will go totally blind, but I know if that day really comse, I will have the support I need.

I read somewhere that unlike humans, birds can regenerate their eye nerves if they are damaged. I think this is because God is fair, a bird cannot live if they are blind, they will fly into buildings! but human can change and adapt, if you can't use your vision, use your hearing. There are people that are less fortunate than me, especially those who are blind and deaf. Can you imagine what life would mean to them?I get my inspiration from other people who are struggling more than me. I've read of a teenager who became paralyzed neckdown aftter a diving accident. He went on with life using pencil in his mouth to follow classes in his university Can you imagine me complaining that i have to use my hearing when a person can single mouthly pick up the keyboard letters one by one with his mouth?.
