I would like to know how in the world do you keep your family happy when you are working nights and weekends.
You don't work every night or all weekend.
If you can set aside just part of one day per week you can really improve your performance chops and your pocket cash.
Go out for four hours on Sunday nights. Set that aside as your time. Of course you have to find a pitch that is close to your house.
I work in Harvard Square here in Cambridge, MA. By day I work as a computer network engineer. I took a job for a company based in you guessed it, Harvard Square. After work I can walk to my pitch from my day job. It is a half block away.
About 50% of the reason I took this job was because of it's proximity to my pitch.
It can be done you just have to be clever about where you work.
