“You do not rise to the level of your goals. You fall to the level of your systems.” -James Clear, book Atomic Habits
If you seek affirmation about whether you should do the thing in your head…
Instead of just telling someone (ideally a trusted confidant) your idea, show them your plan. Your work plan. Your system for executing the idea. Complete with estimation of project length, action steps, arbitrary deadlines, budget, contingencies, and anticipated obstacles.
While the idea is fun to talk about, the work plan is the true mark of someone who’s serious. Serious enough to be taken seriously.
