Life at work part 1

i recently returned to work from 3 months of time off, when i returned I made sure to maintain a positive attitude towards everything and everyone around me.  I enjoy my job and I make it better by creating a positive lifestyle there as well.  Last week one of the night maintenance colleagues asked me, after all the B.S. i was dealing with, how was I able to come to work everyday with a smile on my face, and keep it there all night (11hr shift)?  I simply told him I keep a positive attitude in mind and always stay focused on that.  He then asked me how I get that (the positive focus)?  I said, I read! He seemed a little amazed, and i asked him if he wanted one of my books, he happily said yes!  I am thrilled that I have been able to influence others around to want to feel the same as I do.  I will continue to move forward, as I hope to have interactions with people that inspire positively or not at all.
