I'll go first I guess....
1. I feel that I have definitely changed as a person, especially in light of the situations I've been in and what I've learned about myself and other people. Has this been an improvement in me, in the type of person that I am? I'm not in a position to say, only someone who's known me for a long period of time could tell you anything approximating an answer.
2. I have been able to control majority of the thieves, anger is still one that needs control. I do feel like I've bottled up a lot of anger inside over the years, I need to learn to let it go and not to let things (and people) get to me now. I know that's a long, hard road but every journey starts with a single step, and I feel I've made a few already.
3. I feel like I've become a slightly more knowledgeable person due to knowing more about my faith, doesn't make me better or worse than the next person. Besides which, to be a decent human being is the important thing, you can learn to be a decent Sikh afterwards.
4. I haven't changed any of my negative traits, I may have more control over them and not let them manifest as often but I wouldn't say that it was a successful change by any stretch of the imagination. I would like to be more courageous, stand up for myself and others more and stand my ground when my views are challenged. If our Gurus could stand up for what they believed in and for the freedom of others, then I should aspire to do the same.
Hope that's of some use, apologies if I may have offended or upset anyone with what I've said.
