I recently got surgery and during my healing period I felt severely disabled. I was in constant pain and had severely reduced mobility. Of course nobody expected me to do any heavy lifting or work. But what made me happy was doing small things nonetheless that weren't expected of me that helped others. For example I was obviously the last one to leave the bed in the morning. But I would still try to straighten out the bedsheets, puff out the pillows and open the window to let some fresh air in. There are small simple things one can do around the house that in sum amount to a lot. Most people rather do the big chores all at once but neglect small but constant maintenance. If somebody could keep up with the small stuff, others would likely very much appreciate it.
