A  typical lion tamer (驯兽师) in people’s mind is an entertainer holding a whip (鞭子)and a chair .The whip get all of the attention , but it’s mostly for show .In reality , it’s the chair that does the important work .When a lion tamer holds a chair in front of the lion’s face , the lion tries to focus on all four legs of the chair at the same time .With its focus divided , the lion becomes confused and is unsure about what to do next .When faced with so many options , the lion chooses to freeze and wait instead of attacking the man holding the chair.

How often do you find yourself in the same position as the lion ? How often do you have something you want to achiever (e,g. lose weight , start a business , travel more ) –only to end up confused by all of the options in front of you and never make progress ?

This upsets me to no end because while all the experts are busy debating about which option is best , the people who want to improve their lives are left confused by all of the conflicting information .The end result is that we feel like we can’t focus or that we’re focused on the wrong things , and so we take less action , make less progress , and stay the same when we could be improving .

It doesn’t have to be that way .Anytime you find the world waving a chair in your face , remember this :All you need to do is focus on one thing .You just need to get started .Starting before you feel ready is one of the habits of successful people .If you have somewhere you want to go , something you want to accomplish , someone you want to become ….take immediate action .If you’re clear about where you want to go , the rest of the world will either help you get there or get out the way .
