A lot of people don't live their dreams because they don't pursue something they love enough.
When I was carless and living on a lady's couch, I'd ask people, "Would you do this if your dream was on the line?" More often than not, they'd respond with, "I don't know."
If you answer, "I don't know if I'd do something uncomfortable in the short-term to pursue my dream," your dream simply doesn't excite you enough.
Dig deeper until your dreams keep you from sleeping at night. Let your emotions fall into something you can't live without. Fall in love with something that you'd want to jump into the unknown for.
There's nothing like it.
