Stretch

I typed "stretch" into dictionary.com and this is what i came back with:
–verb (used with object)
1.to draw out or extend (oneself, a body, limbs, wings, etc.) to the full length or extent (often fol. by out): to stretch oneself out on the ground.
2.to hold out, reach forth, or extend (one's arm, head, etc.).
3.to extend, spread, or place (something) so as to reach from one point or place to another: to stretch a rope across a road.
4.to draw tight or taut: to stretch the strings of a violin.

7.to extend, force, or make serve beyond the normal or proper limits; strain: to stretch the imagination; to stretch the facts; to stretch food to feed extra guests; to stretch money to keep within a budget.
8.to extend or strain (oneself) to the utmost, as by intense exertion; tax.
9.to increase the quantity of (a beverage, food, paint, etc.) by dilution or admixing: They caught the bartender stretching the gin with water.
10.Radio and Television. to prolong or slow down (action or pace) in order not to end too early: to stretch a show; to stretch the action two minutes.

However i personally think "strech" means to push yourself, for example trying to leanr a new language, education stretches each person to different levels for example when you first learn to read and write it pushes you to understand and gain knowledge of the topic in question even if it is the plot of the story.
