What's worked for staying consistent with DSA after a 10 hour workday

Been full time for a year and still trying to prep for a jump to a bigger company. Longest streak I've had is six weeks and here's the only stuff that's actually kept it going:

• 20 minutes, not an hour. An hour never happens on a bad day, 20 minutes almost always does.
• Same problem set as the day before if I didn't finish it, no new problem until the old one's closed.
• Phone timer, not an app streak. The streak counters made me anxious about breaking them, which made me want to quit entirely after one miss.
• Zero LeetCode on Fridays. Turns out having one guilt-free day a week is what keeps the other six going. Not saying this is optimal, just what's survived contact with an actual job.
