Is to do it regularly.
The second rule is to never skip it.
If you skip it just once, you'll continue skipping it.
Until one day you've stopped doing it for good.
Creating stuff and putting it out there is hard.
You'll get rejected.
By almost everyone.
And you'll feel like giving up.
Practically every single day.
That's why the only way to be able to keep doing it is to keep doing it.
There really is no other way...
