How to achieve consistent daily practice

If it's easier, it's right.

The easy way is always the right way.

Seek instant gratification.

The hard way is always the wrong way.

Set a timer and practice. Follow those rules. See what happens.

You won't know unless you try.

It's your best shot at a consistent daily practice. I don't know of another way.
