It's more the final line, there, than anything else.Trouble with spending discipline? Sounds familiar... hahaha!
Just withdraw cash and put it in en envelope and write "A5E kickstarter" on it.
That way you will have it in reserve and it's harder to spend money that you do not have on your account balance on some stupid things in the meantime.
Ofc, you always have option to spend the cash if there is some dire emergency :/
In my family we have a saying: "If things are going well: just wait."
Last year we had to replace the transmission of one of hubby's work vehicles (Postal Worker) which wiped out about 2 months worth of saved up salary. This year we had to put another $1500 into the same vehicle to replace all the brakes, rotors, two tires, one wheel, the list just goes on and on... Not to mention the right-hand steering/pedal modifications.
Everything'll be going fine for 2-3 months and then BAM! one of the cars is out of commission or someone needs dental care or some other $1k+ expense jumps out at us from nowhere.
Things have been fine for just under 2 months, and I have the cash to throw at a kickstarter. So right around the next corner...
