I read an interesting blog post by Seth Godin. He's a best selling author of many many books and has been writing a blog on marketing, business and life for about 10 years. This particular post was called What's In The Box? It's premise is that if you spend all your time worrying about what's going to happen ... then nothing is going to happen. And you've just worried yourself the whole time and still didn't get anywhere. You may as well have just gone ahead and done something and saw what happened. (here's a quote because he says it better than I do)
"...All the wishing and planning and imagining isn't going to change what's already in the box. The act of opening it doesn't deserve anxiety because the contents of the box were determined a long time ago."
That's not to say that life is predetermined and you get what you get no matter what. It also doesn't mean that you don't have to plan anything. It just means that worrying about an outcome isn't worth the time. Planning yourself into paralysis isn't worthwhile either. Just do something and see what happens. Then adjust from there.
Feel the uneasyness but move forward toward done.
I've written similarly about this previously If you want to do something. You have to do something. And Sometimes good enough is good enough. (Hmmm, after looking for the link, it seems I haven't actually written about the second one. You can look for that blog post in the next couple weeks.)
Basically what I'm saying is I've been too busy planning and worrying lately with not enough time spent actually doing.
