Good job man. And you're losing at a reasonable speed. Too fast is bad, and statistically comes right back. Just keep at it, and start thinking about what your maintenance fitness and diet routing will be once you hit your target. Personally I don't like weight goals at all. A more vague (and significant) goal would be "to be active and eat healthy". Slow and steady, a diet and exercise program you'll be on for the rest of your life.
