Looks like it'll work. Is your £30-40 per week? It seems about right.
I did a food experiment back in October in which I lived off of $29 per week (starting from absolutely nothing) with additional 'challenges' - I actually blew past that and ate for three weeks on just two weeks budget.
£40 a week is comfortable - I'd struggle on less as I like my fruit too much. When Summer comes I clould live off less with allotment pickings.
<$30/ week is a stupendous effort!
Yeah, the average cost per day came out to $2.09
Great effort! Something for me to beat, but I won't be 'in the zone' until August/ September! By which time we might both be even gladder that Steemit is an incredibly minor part of our retirement portfolios.
