Drawing just one card from the deck is the easiest and probably the most common method of doing a reading. Without a storyline like when interpreting a spread, there are no cards to compare and contrast. You can simply interpret the card as the answer to your question.
Alternatively, you may use this method repeatedly in succession to let the cards tell you a story.
10 of Wands
A man oppressed by the weight of the ten staves which he is carrying.
A card of many significances, and some of the readings cannot be harmonized. I set aside that which connects it with honour and good faith. The chief meaning is oppression simply, but it is also fortune, gain, any kind of success, and then it is the oppression of these things. It is also a card of false-seeming, disguise, perfidy. The place which the figure is approaching may suffer from the rods that he carries. Success is stultified if the Nine of Swords follows, and if it is a question of a lawsuit, there will be certain loss.
