The energy & motivation. Since starting July 3rd, 5 jabs in (six after tonight), I walk an hour a day (suddenly I can find the time), I have redone my whole office, stripped & gutted half the garage far, replacing old wooden shelves with new steel racks, began resistance sessions thrice weekly, and began cutting the genuinely grass again. Oh, and I dropped 10kg plus my joint pain, inflammation & a clothes size. If my wife suggests a weekend task involving movement and planning, like the garden or garage, I've made plans and started before she's done. It's like I've suddenly got more time every day & my wife is running low on chores for her list lol.
