Why does waiting one week feel impossible today but easy a year from now?
You would never wait a week for an extra $5 today, yet you would gladly wait that same week a year from now.
Present bias is our habit of over-weighting rewards that are available right now. We discount the future on a curve that is steep up close and flat far away, so anything immediate gets an outsized pull. The tell is that our preference flips the moment a choice stops being about now: waiting feels unbearable today but trivial when both options are far off.
You promise to start saving next month, but this month there is always a sale, a coffee, a small treat - next-month-you keeps inheriting the discipline that today-you spends.
When now is one of the options, it gets an unfair advantage - so the gap between what you plan and what you do is widest in the present moment.
If you want to save or stick to a habit, remove now from the menu: set up an automatic transfer so the future-you decision is locked in before today-you can grab the immediate treat.
Present bias = the reward closest to your hand always looks the biggest.
