My advice is simple; as cliche as it may seem, take the time to read The 4-Hour Workweek by Tim Ferriss. This book addresses most of the psychology behind your discontent and offers a slew of energizing solutions that should help get you out of the proverbial rut.
If I may, here's a great poem a wise man once shared with me:
Take time to think...It is the source of all power
Take time to read...It is the foundation of all wisdom
Take time to play...It is the source of perpetual youth
Take time to be aware...It is the opportunity to help others
Take time to love and be loved...It is life's greatest gift
Take time to laugh...It is the music of the soul
Take time to be friendly...It is the road to happiness
Take time to dream...It is what the future is made of
Take time to give...It is too short a day to be selfish
Take time to work...It is the price of success*
*in healthy doses
I was in your same situation. Once I managed to find a way to work remotely now I'm able to organize my time more efficiently and find time for my side projects/ideas.
I started a number of sites like that years ago in college, with nothing but a static site built with a cheap template in a day, and some AdWords credits. If people actually signed up to learn more, or ordered a product, or whatever, then I'd spend the time building a real business around it.
The first time I saw that written down was in Four Hour Workweek several years ago. Now millions of people have been told to do the same.
