Get the ball rolling

The first few words are the hardest. Especially after some time away from the keyboard.

Same thing when heading back to gym after being on holiday.

Or studying something you've forgotten about.

It takes about as much time to get back into it as you've spent away from it.

Momentum is valuable. If you have it, keep it.

If you've lost it, work to get it back. It'll be there somewhere.
