stop keeping up with everyone.
Its very doable, reduce everything, cut out costs on things you really don't need. needs are real, wants are a fantasy.
set a realistic budget.
I wish you luck, you can really do it.
Work out how much you want to save and by when, then figure out how much you have to put away each week to achieve that. Then you work your budget, cut things out, reduce costs wherever you can (shop around for insurances, phone providers etc) to make your goal achievable - adjust your timeframe if your target just isn't possible though.
