You're like Annie, positive that tomorrow will be a brighter day. You're Pollyanna, seeing rainbows where others see a hunk of glass. That attitude is admirable, but sometimes you can be a little overly optimistic!
Watch out that your expectations of how something is going to be or feel, or how others will respond to you, are reasonable. You could be setting yourself up for disappointment otherwise.
First, list what you expect from that job offer, vacation, reunion, party. You'll see which ones have legs. Then concentrate on only those things you can control. You don't know that your boss will love that report, but you can do the best job possible.
