I had the same problem with dips a couple days ago. Second set was way easier than the first. I think I'll have to warm up a bit more with feet on a box or something.
I'm certainly not someone to listen to about technique but it it looks like you almost free fall when squatting. It doesn't seem like it would be good to drop so fast to me as that means you have to stop a fast moving weight at the bottom. I haven't seen other videos where people drop so quickly. Rip doesn't drop so fast

Organizing time and making sure priorities get the necessary amount of time is never luck. If your workout is important to you then figure out how to make the time you need. Life is always busy so learn how to make time for exercise now and you will be able to exercise regularly for life. I've seen many friends loose control and also loose their exercise time. Take control. Use discipline.
Great log with good reflections. Thanks for sharing it.
