Save pretty much never .. since I was kid .. student .. work ..
Only time frame I did saving, was when I was with my EX .. ( she was kind of totally different type of person to me ) So, I did save quite a bit that 5 yr... ( original plan for wedding, downpayment .. etc )
But it didn't work out with her anyway .. so I bought 2 cars, spent all the money .. screw up!!
I know my annual salary. But when I put savings aside, I took $ from every pay cheque and put aside for saving. But at that point I just base on how much after tax, to decide my saving.
