For talking about personal cash management, specially for wagies.

This month I will probably finish to pay all my debts related to credits and cards so I was wondering how to separate the money left for savings (20% of income)

Let's say I have three priorities in savings:
- Important but not vital surgery that improves my life at around $5000
- Getting a brand new laptop for my work of roughly $2000 (been using a government worn device for 15 years)
- Buying a house $??? (student that lives with his parents, started college this year)

Should I do a full investment into the most important thing on the list (surgery) or will it be better to invest slowly into the three objectives based on percentage of the savings pool?

I already have three months of expenses for emergency (unemployment or health)

All advice welcome!
