Cut my LeetCode grind from two hours a night to thirty minutes and somehow still landed the offer

Was doing two hours every night after work for about ten weeks, started dreading opening the laptop, quality of practice tanked even though time spent didn't. Cut it down to thirty focused minutes, no phone, timer on, one problem, actually review the solution after instead of just moving to the next one. Felt like I was doing less and slacking off. Interview performance didn't drop, if anything felt sharper because I wasn't running on fumes. Wish someone had told me sooner that exhausted practice doesn't compound the way rested practice does.
