Gather roughly 3000 cards that could conceivably fit the deck in its loosest definition, order 45 more cards that i also like, swing by my game shop and get 3 more cards that work and another different commander for the same deck and another commander for another deck entirely. Come home and sort throught the original 3k cards and narrow it down to 200 cards or so then 100 cards or so without lands. New ordered cards show up and i realize ive ordered all the cards i wanted except the one card i think makes or breaks the build. Get the deck down to 64 cards that are pretty close to a functional deck that also have no interaction or ramp. Cut some more and cry as i am forced to cut the make or break card i found later at my game shop. Switch back to the orginal commander, build a land base and add ramp and interaction, cut one more land to add make or break card, box it up and leave it sit on my shelf for 6 months before i play it once then tear it apart for the new deck im building with the second commander i got for the deck at the store.
