So i've read the 4 hour work week by Timothy Ferris and I have to say it's one of the most motivational pieces I've ever read. I say read but i did not do this I listened to it on Youtube. Some guy with a very nice voice told me about all this stuff. What a great book and the reader was very into the whole cituation making it even more impressive.
All in all here is a quote I do try to keep in mind:
“For all of the most important things, the timing always sucks. Waiting for a good time to quit your job? The stars will never align and the traffic lights of life will never all be green at the same time. The universe doesn't conspire against you, but it doesn't go out of its way to line up the pins either. Conditions are never perfect. "Someday" is a disease that will take your dreams to the grave with you. Pro and con lists are just as bad. If it's important to you and you want to do it "eventually," just do it and correct course along the way.” ― Timothy Ferriss, The 4-Hour Workweek
You can find the book on sites like amazon or any other prefered bookstore you might like to get your books from!
