mixed feelings about today's workout

Today's workout was a series of letdowns and failures but in the end it was a good workout.
here's how it went.

told my self "i'm going to do 500 thrusters for time"
got to 100 and decided i wanted to do something different.

Told myself "i'm going to do 100 bent over rows @ 135lbs.
got to 60 and decided i wanted(needed) to do something else.

told myself i was going to do 100 bench press at 85lbs
Got to 60 and decided i wanted to do something else.

told myself i was going to do 50 bodyweight dips.
got to 25 and decided i needed to do something else.

told myself i'd row 4K getting off every 4 minutes for 20 honest pushups.
got to 2000 meters and decided i should go home before my ego took any more abuse.

It was kind of a letdown because i was very disappointed in my inability to make myself complete each task i set out to do. Just another reminder of why i need to work out in the company of very hard working, motivating, and supportive people. Working out at 24hour fitness where people dont really workout is very tough. i would have been better off just doing the 10am class. that would have required waking up earlier though. Oh well. Got a great bike ride in the rain.
