1.) Increase my income. This is partly financial, partly academic since I do need to be building a professional portfolio as a graduation requirement anyway.
2.) Stop stressing over money. We've weathered some really terrible financial setbacks with less stress than I find myself expending now over relatively minor bumps in the road. That is counterproductive and needs to stop!
3.) Plan better. My first semester back to school was far more expensive than it had to be, mostly on convenience purchases like lunches out (that I don't even enjoy - I hate most fast food!), prepared food or restaurant dinners when I didn't think to thaw something or plan ahead for a late evening, etc. Reining in the "stupid tax" of library late fees and buying things that I forgot at home along with getting a better grip on the overall food budget will free up a decent chunk of change.
2015 is going to be a very expensive year for us, lots of camp and travel plans on top of tuition x 3 (two private elem, one college), so I'm not setting specific savings/long term planning goals. I am taking the approach of getting the little things right and trusting that they'll add up to measurable results in the bigger picture.
