There's a myth out there that you're probably falling victim to. It's not just you, this myth has gotten most of us at some point. It will most likely get most of us a bunch more times in the future too. This myth has been around for so long that we just accept it as truth. No one even questions it anymore. The myth is that you're "too busy". I know that you're busy. You've got work and family. You're even trying to squeeze in some semblance of a social life. Most days you wake up not knowing how you're going to get everything done and you go to bed wishing there were at least a couple more hours in the day.
All that being said, you're not "too busy". It's a myth.
I know it's a myth because you start new things or add onto the things you're already doing all the time. For instance, when you're boss came to you with that new "important" project you didn't tell him/her you were "too busy". Also the spring sports season is about to start, are you going to be "too busy" to drive little Timmy to soccer practice? Or what about the time your friend got tickets to that hot new show and they invited you to go with them (this probably included dinner before and drinks after too).
The amount of time in the day didn't change but you somehow managed to do all those things and everything else that you would normally do.
See you're not "too busy". It's a myth.
So what gives? You do stuff when you're motivated enough or when you want to enough. You don't tell your boss to shove the new project where the Sun don't shine because losing your job would be a bad thing (motivation). You make time to drive to soccer because you could never disappoint little Timmy (want/motivation to be a good parent). And you ain't turning down that ticket because it's the hottest show in town plus you get to let loose for a few hours (want).
See we're motivated and want to do lots of stuff. The thing is those wants and motivations have to be high enough for us to act on them. If we are going to act on them, they also have to be high enough for us to either change or eliminate things we would otherwise be doing. Most of the things we're motivated and want to do don't meet those two criteria (and they probably shouldn't, it's not necessarily a bad thing).
This is where the myth comes in. We need a reason to explain why we didn't do all that stuff we were motivated and wanted to do. It doesn't sound or feel good to admit that you didn't care or want to enough. We all want to feel good, especially about ourselves. So the "too busy" myth works wonders. It gives you a convenient out for why you "can't" do something and it lets the person you're telling it to off easy.
Just remember you've made a choice, you're not "too busy". It's a myth.
