When considering self-sacrifice, it is also important to weigh-in the effects on other people. IE, every person that “sacrifices something for the cause” increases the perception that “if you want to work on this, you need to give up stuff”. This might in turn turn people off from joining the cause in the first place. So even if the sacrifice increases the productivity of that one person, the total effect might still be negative.
