Time

You tell yourself you'll do it when you have time. You're just waiting until you have time. But you aren't going to just "get" the time.. And it feels like forces are working against you even more because you have that thing you want so badly to do. That's why you can't wait until you get time, you have to make the time. You have to carve it out - before or after work, during lunch, late at night before bed. You make the time.

For me it's writing. Maybe it's something different for you.

Make the time.
