I try to make whatever I'm learning fun and relatable. That means making it not boring. Usually I don't follow any technique I just set a goal and mindlessly try to achieve it by learning things along the way. If it's a programming language I start with a project. If it's a mathematical or physical concept I implement it, use it or explain it to someone else. I usually go to Wikipedia or a good textbook then slowly start diving into the literature. I usually then read a recent review paper and one of the old seminal papers related to the topic.
