I found myself asking similar questions about a year ago and stumbled upon a book called Be Your Future Self Now, by Dr. Benjamin Hardy that helped. After reading the book, I:

1. Created 1 to 3 goals that I want to accomplish in the next 1, 5, and 10 years. 2. Evaluated all my activities. 3. Eliminated all activities that aren't actively driving me towards those goals.

Once I eliminated superfluous junk from my life, I felt a lot more focused.
