Happens to me all the time also. Get started on something and then something else pops up so concentrate on that and then another thing.....on and on. Plus I get tired of doing tradeskills all day and will switch to something else.
I might suggest dumping the spread sheet idea, I spent more time updating that than playing the game. I use the Hero's Journey a lot now to track what I need to do. Since it shows which missions and tasks etc.
Couple things I like to make priority:
Get the tradeskills as high as you can. The best aug in the game takes 350 in all. Most players still wear it at level 130. There are lots of guides but I tend to get lost reading those and again, time is gone. So I just google what I need now. Like cheap pottery at level ?? in eq. Always have the eq at the end. Even a half an hour a day will help.
Since part of that aug is POP flagging and that can be real easy with our higher levels now, I try to get that done sooner
Progression and ports. There are a few zones, like in TDS that require you to do the progression, or for the ports you need to do all those in West Karana to attune yourself. Get these done and out of your hair so you can move around freely. There is an NPC in Degmar the Lost Castle (that is in TDS) that sells breadcrumbs, well they are free but he is the only way to get a good quantity of them. You could forage in POJ but that will take years.
