When you have no clue what to write next, just put your pen on the paper.
When you have no clue how too swim, go back in the water to practice.
If you don’t know how to cycle? Push the pedal.
Many stuff worth accomplishing is as hard or even harder than we think. But the next action is clear.
The trick is not to do all at once, the trick is to continuously determine the next move and make that move.
