I practice my saxophone three hours a day. I’m not saying I’m particularly special, but if you do something three hours a day for forty years, you get pretty good at it.
What I’ve learned from running is that the time to push hard is when you’re hurting like crazy and you want to give up. Success is often just around the corner.
If you make your internal life a priority, then everything else you need on the outside will be given to you, and it will be extremely clear what the next step is.
