It is disheartening.

I would highly recommend, and this is something I often do, is when I have a long survey , I take a break for five minutes or so and either have some tea or I do some videos to keep the earnings flowing.  That way when I feel I am ready to continue the survey and then later get dq'd I don't feel like I waste so much time.  For example:  If a survey has already taken me 15 minutes, I usually stop and do a few videos and then finish, or do the same thing again if the survey is still going after 30 minutes.  I hope this helps someone as much as it does myself.

I would be careful doing that though because some surveys will kick you out for taking too long outside of their targeted time

Kick you out when taking too long, decline/reverse payment credit when taking too short... #JustCantWin

Seriously though, I've only encountered one company's surveys that automatically kick you out for taking too long. It's those AMx ad surveys. Be mindful of your pace if you encounter those. Good thing is their surveys tend to be short and straightforward, so they are easy to complete straight through.

I blame capitalism.

I know the feeling. But I must say on this site I have never had it happen to me much. Also I don't think I have spent more than 15 or 20 minutes and got disqualified. It is very irritating but it happens to most any of us.
