Another user recommended The One Thing, and I'll second that. You have to always be prioritizing. Figure out what you really, REALLY want to do, and you will make time for it.
I definitely suffer from the "everything looks cool and fun" syndrome. There are a thousand things I want to learn and only enough time to learn maybe three of them.
You can do anything, but you can't do everything. So how do you decide what to do?
I also use a Full Focus Planner and the corresponding method that goes with it, to distill annual goals into quarterly, monthly, weekly, daily habits. FFP is definitely not for everybody, but when I commit to using it I do find I get a lot more done. Then I invariably fall off the wagon.
We're all a work in progress.
