Reps over hacks
Hacks fade with the trend. Reps compound.
A hack is borrowed. It works until the thing it depends on changes, and then it is gone, and you are back where you started.
A rep is yours. It does not expire. Every one you put in makes the next one easier, and they stack in a way a hack never can.
Chase hacks and you are always starting over. Stack reps and you are always a little further up the path than you were yesterday.
