What do you do after completing Skyrim's main quests (Vanilla, Dragonborn, etc.)?

Was wondering how many people are completionists and how many people get bored right away after completing the game (so to speak). I personally get tired of a character after Lv. 40-50ish and decide to try a different playstyle.

I like having goals for my character, and when they are met I quickly get bored. That usually happens around lvl 40-50. If you're playing a character class of some type, without legendary skills, you quickly run out of skills to improve. Then tends to be around level 50 or so.

My current character has the highest level I've ever been, 68. And it's only because of legendary skills. I'm making it a goal to reach lvl 75 before I quit and go do something else. I can't see myself making it all the way to 81, but who knows. I still haven't finished the main quest.

I start a new caracter, when i finish the main quests, after, i loose my motivation to continue.
Max level in 1 year, ... lvl48!

Once I finish the main quest, I mainly mess with mods or try to complete guild quests (mostly the College of Winterhold or Thieves Guild quests).

I don't play in any logical order. I just explore and go as I please. I have not yet got bored.
