Well, it is as it says on the tin. A plan which can be used to give your life direction. Think deeply. What is the future that you most want to see for yourself? Write that down. Any route that appeals more than others? Keep a memento of that. And then work backwards. How can you get there. What do you need to do? What skills would that role require, and do you have it already? If not, how do you go about getting it?
Well, I can only use my own example in this instance. I find it helps me to move forward. When I face setbacks, and my My template life plan - Dates from when I made it and underneath the age I will be at that timerecent unemployment was one of those, I can look at my plan and tick a few things and think, by gum, it's not as bad as it first appeared. In fact, let's turn it into a blessing and just move this step forward a little bit and use this a little differently. In other words, it grounds my ambition and gives me something tangible as a waypoint. I like it, and I think it is a very underused tool.
If you are anything like me there will regularly be times when you panic slightly and think "ohmygod, I'm 26andstillnotdoingthisorthat..." but actually knowing where you are and where you want to get to does help with this. I'm a chronic over-thinking but feel much more content on my path since I have built my plan. It's a little thing, and takes no more than an afternoon at most, and yet it brings me courage and drive, and those are both brilliant things to have. It stops me sweating the small stuff, cause I have the big stuff ordered in my head so what else is there to worry about?
Don't dismiss the idea of having a life plan. Build one and see what happens. It might just help you get to where you want to go.
