Dont lose faith Chopsie , you are almost there mate , I started in 05 with a 175L tank and was empty by 12 every day and needed to refill , i then added a 250 , that was not enough so had the 175 and a 350 which was enough
Now 12 years in i have cut back to just a 250 alone , ok , i only do 5 hours a day tops , but today i did from 10.30 to 3 , i made £140 and came home with just under 50 L left in the tank , its a learning curve that takes time thats all , im no big earner but i do what i want to do and go home with enough wedge to pay what needs paying, and have a bit for a rainy day
