There will come a time on a path to achievement when coasting along will no longer suffice (this should be around day two).
You would be forgiven for thinking that the challenge will ramp up gradually and increase every day. What really happens is that you run into a brick wall.
Leo wrote a brilliant post recently that illustrates the danger of doing anything we don’t want to become good at: every time we do it, we get better at it.
Anything worth doing involves the brick wall experience and while it’s tempting to postpone what’s needed (getting through, over, or around it), you’re just getting better at ensuring that the challenge is never addressed properly.
