Living in London was quite expensive for me. He estimates four months:
"All my expenses come from the £10k but I can only make money from products (e.g. no consulting). London is expensive, so this gives me about 4 months."
"All my expenses come from the £10k but I can only make money from products (e.g. no consulting). London is expensive, so this gives me about 4 months."
Bear in mind it's not £2.5k/month for living expenses: it's £2.5k per month for all expenses: including building the product, etc etc.
