The first thing is to choose the size of the cigar, depending on how much time you have for a smoke. For after meals, a large one may be fit. For after breakfast or breaks, a short and thin one is more appropriate.
In regard to strength or smoothness, it is up to you.

Cutting the tip
After verifying that the chosen cigar is in perfect state, without cover cracks, smell the aroma at the end of the cigar, where it is more intense. To cut it we recommend the special guillotine with one or two blades, a scissor, or a circular knife, assuring that they are sharp enough. The cut must be made without eliminating the little roll that fixes the filling to the cover. Never cut it with your teeth, disregarding your wishes to appear rustic or authentic, it will undoubtedly spoil the cigar.

Lighting a Havana
The more traditional manner is with a wooden match, but a gas lighter is also acceptable. Gasoline lighters or candles spoil the cigar's aroma.
Do it slowly: place the flame near the end of the cigar and let it scorch a little, blow it slightly, put it in your mouth and suck it while lighting it, rolling it between your fingers. Make certain that the lighting is uniform.

Smoking  

Do not inhale the smoke, but enjoy its taste as it runs through your palate. Do not dip it in coffee, whiskey, or in any other beverage. Do not flick the ashes constantly, rather let them fall off or flick them if they grow very long. If your cigar goes out, flick the ashes and light it again.
When finished do not ground it , but rather place it on the ashtray and let it burn out.
