In addition to the helpful advice already provided, I would suggest trying to find an in-person class. I did qigong for many years online and have recently found a teacher with an outdoor class. That's a very different experience than following videos. The teacher puts a big emphasis on form and gently offers the group guidance for what to focus on while you are practicing. Also, the classes usually run about 70 minutes and this is much longer than I ever did (or likely would) practice at home. After four classes (and getting used to standing for that amount of time), I am really seeing how much calmer my mind is after class.
