I personally would love a year to 18 months solid on installs then the same on breakdowns. I'd be flying then.
At the minute i'm mostly doing maintenance work, gas safety checks, about 1 install a month and a few breakdowns. It's a very long winded way for me to learn but i'd rather be doing it this way than having to wake up every morning and start the job hunt.
I was unemployed for about 6 weeks when i was 19, naively i left a job thinking i would get a new one within a few days. I swore to myself i would never leave a job again without something else to go to no matter how fed up I got. It means I have to eat carp from time to time but anything is better than being unemployed.
My dad always says life can be hard but it's a lot harder when you got no money coming in. All of lifes problems are worse when you are skint. Just stick at it, as each month passes you are notching up the experience.
