Work has a funny way of working itself out. It rewards those who put in the work.
Work is supposed to be hard. It never really gets any easier, you only get better at it. If you feel it's getting easier, you probably aren't challenging yourself anymore. If you feel like you don't know how to quite do something, or you've run into a road block, you're probably on the right track.
If something seems difficult and you have an itch to go after it, that is precisely the thing you should do.
Or don't. But that rarely works.
