Good habit/ Bad habits

I was cooking a meal for my mom the other day and I noticed a bad habit. I cook with my mouth. Yep, I taste everything while I'm prepping and cookin for a meal. How many of you eat while you're cooking?  I'm such a taster and sampler that I am too full to actually sit down and have dinner with my family. So I watch them eat and end of cleaning up the kitchen. I know it's such a bad habit, but I just can't seem to break it, suggestions?
