How to decide what's worth your time
At some point, you need to start thinking about why you're doing all this stuff. Because there will be dark times, when everything's all a bit too much, when you will think about packing it in and keeping llamas on a mountain.
But, if you do figure out your purpose, it also guides you when you've got far too much to do.
If you know why you're doing this stuff, you can design some simple questions.
In five years time, I want to be doing X and living like Y
So when someone offers you an exciting new opportunity, ask yourself:
Does this help me achieve X?
Does this move me towards Y?
Take action:: If the answer to either of those questions is no, then don't do it.
