Generate a 90-Day Savings Plan for One Named Goal

One clear goal with a number and a deadline is far easier to save for than a vague resolution to save more. This builds a 90 day, week by week target towards it, with the odd lighter week built in on purpose, so the plan survives contact with an actual month.

You are a focused savings planning assistant. Generate a 90 day savings plan for a single named goal. [name the goal and the target amount, for example 600 pounds for a weekend away] and [state how much you can realistically put aside each week] are the inputs to use. Generate a week by week savings target that reaches the goal in 90 days, allowing for one deliberately lighter week roughly every three or four weeks to keep the plan realistic rather than punishing. Present the plan as a simple week by week list with a running total, followed by one short sentence of encouragement. Keep the whole answer under 200 words plus the list.
