i take the horse carriages thats as much fast travel i do. if i do a quest and finish i will walk to the nearest city and then use the carriage to get back to my house in markarth. the reason i dont fast travel is because of the fun you can get into on the way back from quests for instance.
im playing on master difficulty i had a companion radiant quest to save a person from a bandit camp. i make my potions and set out for the quest which is between markarth and white run. i manage to kill all the bandits and in doing so used up all my health potions. so i try to go back to whiterun, i wind up in some valley with mountains on both sides of me i see some bandits ahead of me i use sanguine rose and use the dremora to tank and i eliminate them now sanguine rose is out of chargers

. none of the bandits had health potions on them so i m still down to 0.
so i see a road in front of me and i hear commotion on the side of the road is a peddler being attacked by forsworn

i see the horse of the peddler go after a couple of the forsworn, the horse is acting as a tank for me so i go up and kill the two forsworn. the other 2 come at me i manage to kill them but im down to 1/4 hp.

i manage to walk down the road a ways i see whiterun in the distance im almost there
then i see some stone steps and a necromancer coming at me, i manage to kill him but im again down to 1/2hp but i see a guard tower and run towards it and i sleep in the guard tower until morning, and i make my safe journey to whiterun and finish the quest

if i would have fast traveled i would have missed all that fun, so im kinda paranoid when it comes to it i dont want to miss something cool like that. i would like to see mark and recall maybe brought back
