Having a single purpose; hence, artless; guileless; single-hearted.
An attitude to life which seeks fulfillment in the single-minded pursuit of wealth - in short, materialism - does not fit into this world, because it contains within itself no limiting principle, while the environment in which it is placed is strictly limited. E. F. Schumacher
At the beginning of his administration, Obama homed right in on Medicare, which he wanted to fix by reducing the overall cost of health care in this country. He risked everything - some would claim he lost everything - by being so single-minded. Gail Collins
I dismiss personal profit and focus exclusively on people and planet. That's what I call social business: a nondividend company dedicated to solving human problems. You can go all the way, forgetting about personal profit, being single-minded about solving problems. The company makes profit, but profit stays with the company. Muhammad Yunus
