If something is a complete new subject to me, then I'm trying to develop an anxiety about failing to learn it. I try to tackle the upcoming problems at any time and thinking about it especially before sleeping, at the morning and while meditating. This forces me to make process but often results in days where I'm very frustrated and depressed, but sometimes ends up in learning new things which I didn't ever expect to be able to understand. Probably not the healthiest way but it works for me.
