There are many benefits to self-denial.  Most wealth is built that way through disciplined savings or investing!  That is not going to happen if you spend today in self-gratification for everything that “you have got to have now.”  Delayed gratification!  Races are won that way.  Companies are built that way.  Health is improved or restored that way.  Short term pain for long term gain!  Live toward the kind of person you want ultimately to be.

“A little sleep, a little slumber, A little folding of the hands to rest”—Your poverty will come in like a vagabond And your need like an armed man.” Proverbs 6:10-11 (NASB)
