I do more with less by attending video tutuorial aviliable on youtube. If I don't understand any subject on class I look on youtube to see if any video class / tutorail aviliable for that subject. Most of the time I found big university's lecture like Standford, Howard,IIT etc. It help me to get more depth knowledge of topic.
I achieve 'do more with less' by using my mobile phone as GPS device. In stead of purchasing GPS i went for a mobile which has inbuilt GPS chip. It saved me cost of GPS and help me call and navigate through one device.. Doing more with less
