Yikes ! This is a bit of a shock to read this because I have never come across someone who dislikes their profession so much? Didn't you realise that optometry wasn't for you during your first year?
I'm hoping to go in to Optometry this year and I think If i do not get a place I will feel extremely upset. I have always wanted to become an optometrist. Not for the money and not for the job but to help other people just as my optom helped me. I have a strong lens and I remember very vividly at the age of 7 (22 years ago) putting my 1st pair of glasses on and I could see the stones on the floor!! I was amazed and that feeling has never left me. I have never been in the situation to peruse my career aspirations until now. I want to help other people so I feel although your pros and cons of the job are very valid, I feel you have gone in to a profession for the wrong reasons?? Excuse me if I am wrong but that is the impression I get following your post.
I hope you find what you are searching for within your career and start to enjoy it as much as I hope to.
