Structuring your goals as projects is key to getting things done when you're doing all the things.
Disclaimer: I'm an organization buff. My entire house is cataloged in my head so that at any point I can walk in and find exactly what I need. By no means am I the best housekeeper--my priorities are read, write, keep offspring and pets in good health, work, then deep clean the day before company arrives, if they were kind enough to give notice.
Organization Skills - Handy, but not required.
If you're not big on organization, or your organization only extends as far as allowing you to somewhat function, don't fret. Project Management is an entire profession of its own but the basic tenets apply and are easy to follow.
The first step is to start with the goal itself. What is it you want to do? It can be anything: change in careers, remodel a room in your house, get a certificate or a degree, compete in a weight lifting competition, start a business, or throw a stealth dinner party. Your goal might be something you have to do or it might be an aspiration. Whatever it is, or however many you want/need to get done, define how the outcome should look.
Now document it somewhere other than your head. Why? Because right now you're focused on the goal, and whether you're anxious or excited about it, that pumped feeling is going to dissipate over time and you don't want to lose sight of what you're working so hard to achieve.
Format Your Project Map
A word of caution: do not get hung up on trying to design the best project management mapping solution--you can get lost in this to the point that you'll have spent hundreds of dollars on software or markers and whiteboards while making zero progress on the project itself. Grab what's on hand. For me, I have a wall and sticky notes, or my trusty notebooks. You might have leftover construction paper and glitter glue pens. Whatever floats your boat, so long as it's something you're comfortable using and it's available to use.
Goal: front and center! Or at the top left. Maybe you like it centered or shifted to the right. No matter your preference, jot the goal down in a prominent location.
Tasks: this are the individual pieces you need to get done in order to complete the objective. They can be as broad or as detailed as you like, just keep in mind that multi-part tasks bundled up as one requires conscious effort to remember each part before it's complete.
Status: create categories for your tasks to fit into depending on where you're at with each one. For example, I have four columns (To-Do, In Progress, Waiting, Done) since those are what helps me keep track of what I've completed, have yet to do, already started, or are unable to complete due to something outside my control. Yours may not be as elaborate. In fact, you can have two if that works better: to-do and done. Customize as you see fit.
Visual or Tangible Feedback
At the start, the To-Do list that seems to go on forever is overwhelming. But as you complete each task and move it to the Done category, you'll have a nice visual that clearly illustrates your progress. This is especially important for projects where you have absolutely nothing to show for all your efforts until you've reached the very end. I've found that this is also the best way to help kids and teens when they're facing an essay assignment with an impossible list of things that must be included. Make each requirement an individual task to work on, and before they know it, they'll have gathered up all the pieces they need and are able to put it all together in a nice final paper.
And that's all there is to managing a project. Oh sure, I'm going to catch flack and wicked side-eye from professional Project Managers for reducing their work into three basic steps, but for most of us, this is the basic gist of how to ensure you achieve complex goals that aren't a simple two-step process.
