Hw do you get around lack of knowledge?

I have a lot of things that I want to do and achieve. Sadly I have a lack of knowledge in alot of the fields that I want to push myself in.

Finding the extra time to acquire these new skills is hard work so I am often stuck in a catch 22 situation.

I need to set a priority and learn about the important skills that will forward me in my life.

How do you deal with lack of knowledge when you need it?
