I learn things by setting a purpose. Eg: For a web project, I need to learn new programming technologies. I have a very sensitive mind. I can't concentrate on multiple projects at the same time. For example: If I'm working in a day job, I can't work on a side project efficiently, I can't concentrate on both my office work and side projects. If I do, My employer could easily figure that I'm churning out. So, If I want to work on a project.. I'll make sufficient money then I quit my job and spend next coming months fully-fledged on my project.
