There really are only 24 hours in a day, 7 or 8 of which are ideally spent sleeping. And a time commitment does take time, but researchers found that if people felt like they had done something for others, their perception was that they had gotten more done than the people who killed time, spent time on themselves or got unexpected free time, and that make them feel like they had more time overall. You don't even have to spend your all Sunday volunteering. The helping tasks in the study took only about 5 to 15 minutes. They included things like editing students' essay or writing a note to a sick child. Time donators also felt like they could do more with their time making them even more willing to give time in the future.
