How many of us want to commit mistakes???

Mistakes are the best teachers!!!!
Last two weeks was a nightmare. My research work is on force feed back control systems.I have been having fun designing the experimental setup which comprises of some fixtures some angle plates to mount the motors and the pulse generating devices.As far as the mechanical portion of it is concerned I am decent.Since it deals a lot with controls, it involves a lot of circuit diagrams, which I am really bad at.I had it all connected once.By the time I started collecting some results I had to send the whole setup for some evaluation.I relied too much on my memory and thought that I could remember the circuit diagrams without any trouble.It took about three weeks to return.Mean while I was asked to do some paper reviews.I lost track of what I was doing and finally when my boss asked me to obtain those results again using some newly designed components I could not, because I had no idea where those wires were connected before.My memory ditched me completely.I realised how important it is to note down things. It took me about two weeks to figure out things to obtain what I wanted.It drove me crazy. It is the best learning experience I have ever had.I enjoyed it, but it was seriously a waste of time and energy.If only I had noted things down, I could have come up with those results easily.It would have been as easy as a turkey shoot for me.

Now that I have learnt this lesson, I would not commit such a mistake again.....
