Percolate or it might be too late

1) Specialisation 

People say, "every cardiologist is a bit of a psychatrist too". 

They could very well complete the job. But is it a good job? And how long will it take? Do your research. 

2) Changing hands

If there are too many dealers, it is time to get rid of the entire deck and change the game. 

Don't be a few cards short of a full deck and think that is normal. It is not. Do your research. 

3) Test 

Litmus. Acid. Sniff. Duck. Red-face. All of the above. Do your research. 

4) Never assume

Or else you will make an ass of u & me. 

It will be foolish of you to think all that glisters is gold. Do your research. 

5) Look who's talking

The one sitting comfortably or the one actually thinking.  Do your research.
