put off learning product design for a year, always pilling up books, videos and courses to take and never took any of them
What worked for me is to put in place a habit.
Each morning, I spend 20-30 minutes making progress on my Udemy courses (that I had purchased long back and never started/completed.)
Since starting this habit, I have already completed one course.
Yes, 20-30 minutes a day may not be much. But the lectures for my course are 5-15 minutes. I can easily finish at least 2 each day. While it will take longer to finish the course (at 20-30 mins/day) at least I'll finish them someday. (Current course has 25 hours worth lectures. So I'll finish them in about 2 months time frame. Not bad.)
If you need help putting habit in place, I suggest you read "Tiny Habits" book by BJ Fogg (Or just watch his TED talk)
