kept switching prep resources every few days instead of sticking with one and it took way too long to notice the pattern

Would do a few days of one course, get restless, switch to a different book, then a different YouTube series, convinced each new one was finally the right fit. Looked back after two months and realized I hadn't actually finished anything. Picked one resource, forced myself to stay with it, and made more real progress in three weeks than the two months before.
