Make a daily, weekly and monthly plan. Compile all the major topics you need to cover over the months. Identify the top resources for each of them from where you will be learning these. Stick to 1 resource per topic because you need to prioritize amidst your work obligations. Make a daily and weekly table in excel. Assign topics to the days, and stick to it as you progress through the week. Be honest to the plan and don't deviate from what you have assigned to learn each day, unless you have an interview coming ahead urgently. Mark the days you actually covered the assigned topic (I colored the cells green if I did, and yellow if I didnt)
At the end of the month, I calculated how much progress I made - chapters completed by total assigned chapters (%)
There is nothing new in what I have shared here. But I really found the act of breaking down the learning path to discrete details, down to daily plans really helped. It almost gamified the learning process for me, and I made good progress too. Take the weekend do this exercise, and dive straight in from Monday (on my busiest days I assigned as little as 30 min, but it helped) Weekends I devoted more time.
Also don't do more than 60 min on weekdays, because it's not sustainable in the long run and you'll burn out, unless you really need to
