It's a post about this: Don't consider the end goal, so much as the process. If you don't lift said heavy ass weights, you aren't going to get jacked. (Steroids help.) If you don't run long, you won't race long. So find something you like doing , do it, commit to working your ass of at it, and see where it gets you. This is not to say that your work will always be fun; but if it's meaningful, if it matters to you and adds value to your life, you'll do it.
