Hey friend, it's me again, I have to say it's a good idea, although I believe it needs a little tweaking that is, some income might be too small to spread at all five at once, doing so in my opinion is maintaining a particular quality of life not really planning to move, I believe it should look more like this;
- Emergency fund
- A little savings to fill up the budget if there's a deficit
- Basic fund (Budgeting occurs here)
- Investment
That's the key ones in my opinion that are necessary for a financially free life.
I did not add the list in any specific order. I felt all these 5 things should be given importance.
Ohh, yh I just suggested which one I think is more primarily than secondary
