The financial climate, the job market, family tensions, Obama moving into the Lincoln bedroom. Even the climate's getting in on the list. Yup, change is everywhere in 2009. If you're not careful, all kinds of strange things might happen in your otherwise ordered life, so it's best to work at avoiding change whenever it rears its head(出现).
Here are 5 ways to do just that:
1．Ignore any opportunities
How many times have you taken a chance, only for things to go wrong? How many times have you seized an opportunity only/'or it to slip between your fingers?
There's always another mess waiting for you, so it's better to stay right where you are. Where you are right now is a known quantity－it's safe, warm and comfortable. Doesn't that sound better than going out there, messing up and looking stupid?
2．Set your expectations low
If you're one of the people out there looking to make a change in 2009 rather than having change made for you, you'd better set your expectations low.
3．Keep on running and don't look back
The best thing to do is to set things out so that you can do everything. It's good to be busy and running around after everyone else will mean that everyone's happy and there's no room for change to happen. It's a win－win!
4．Recognize that most changes are too big
Face it; there are some tasks you're just not up to. Landing that exciting new job, getting a promotion, taking on the 'big project' or building a relationship that really works－these are all big challenges and you don't want to bite off more than you can chew.
5．Ignore that little voice inside
You might sometimes hear a little voice in your head that tells you you're not happy or that something has to change. This little trouble maker can speak up at any time and throw the Spanner of Confusion in the works, and it has only one thing on its mind－to take you out of your comfort zone and make you change.
       Imagine if everyone went around listening to what they really wanted and acted on it－what a mess! No, best to ignore it and carry on with what you're doing.
