I love that feeling of bringing something badly damaged back to life. Now to see what else might be wrong with it...
I know that feeling well. Congrats, you should be happy.
In another life I was an industrial electrician/instrumentation Tech. I worked in a very large factory and was on Call via a cellphone. Everyone that called me had a problem and they wanted it fixed yesterday. I brought many things back to life, it was my job. I always got that feeling you just described.
