Pennies in the Bank

Virtually no matter what, the next morning/day, I will hit the gym.
Doesn't matter how late I worked.
Doesn't matter how much my girlfriend might plead or coyly beg....
Doesn't matter if I haven't eaten.
Doesn't matter if I drank whatever.
Doesn't matter if it's the 5th or 6th day running/in a row. 

The next day I will hit the gym.

Same goes for writing/blogging in some capacity.

I've written probably 10x the number of posts that were just drafts or went unposted than what's actually on this blog and the other one I keep.

You only get good at what you spend hours and hours doing. Period.
Some guys will only ever log the hours I log in the gym when they log into their XBox account. I've spent more time fighting and training to fight than most guys spend in college, post grad, and a PhD.

The only other things I've logged a comparable number of hours doing is my career which I recently took a break from, and writing/blogging.

I think you can only be good at maybe 2-3 things in your life. That's pushing it.

Success isn't a spring. It's a marathon. You must inexorably move toward your goal(s).
Build the skills you care about.
Paint happy trees.
Act in off broadway shows.
Do martial arts.
Start a business.
Whatever.
Embrace the grind of the process of skill acquisition. Patiently yet deliberately and unwaveringly work at it a couple hours almost every single day and some days work the entire day and night and then get up and do it again.
