It's already too late to "plant the seeds" for a big raise, so I'm anticipating some little 1% raise today at my review.
I had my chance a few weeks ago, when I stayed late to confirm and fix a bug that would have cost us a $2M contract, and everybody knows what I did and how important it was. Still, without me actually pushing for a big raise, I know it won't happen. It's a small company and money is not wasted. To pay me a big raise I didn't ask for would be throwing money away.
So why didn't I ask? I think because I don't want the commitment a big raise would impose on me to stay indefinitely, and I don't want to be comfortable. I like feeling the pinch of money, as it keeps me motivated to work on my startup ideas. If I allowed myself to get too comfortable, I fear it might not be the best for me, long term.
