Here’s a hint that may help you achieve your organising goals. Think about a time that you got something done.
What did you do?
Unpack the process… what came easily to you that helped you achieve it?
In other words, what worked? And what didn’t?
Asking these questions and delving into the thought processes behind what made that a success will help you with future projects. If it worked for you that time, there’s no reason why the same principles can’t be applied to other things that you are wanting to tackle. You get more bees with honey, so think about your successes and don’t focus too much on what is left on your to do list.
