Seth Godin:

If you’re afraid to write, write a little, every day. Start with an anonymous blog, start with a sentence. Every day, drip, drip, drip, a habit.

If you’re afraid to speak up, speak up a little, every day. Not to the board of directors, but to someone. A little bit, every day.
Habits are more powerful than fears.

You like photography, take more photos and edit one in Photoshop everyday. If you want to be a better blogger, write something everyday. You want to learn and feel more comfortable using WordPress, then watch a how-to-video or read popular WordPress blogs such as wpbeginner.com everyday. Want to learn new skills, take an online course at lynda.com and complete a chapter everyday.

This is how you become great at something!
