Keep up the progress. Is runecrafting the next 99? 
Umm i guess one of them.
I kinda figured out why I would take long breaks from rs. Was becasue I would grind myself into the ground with one skill. So I am im try to level a few different skills up at same time. E.G theiving to 90 then RC to 90 then Div to 90, etc...
In the hopes of not grinding my life into demon dust. Its sorta working for the time being.
