SMART targets

To make sure I'm not just putting down general goals which I'll achieve by not doing really anything differently. I was told to use a SMART target which gives you a guideline almost in what you should be aiming to achieve. Also a specific goal has a large percentage of achievement than a general goal. 

The 6 W's- 

Who?

What?

Where? 

When?

Which? 

Why? 

Example: A general goal would be, "get in shape" But a specific goal would say "join a gym and workout 3 times a week"
