Endurance is not fun but it builds character. It’s important to find fun in the process. Think of ingenious ways to enjoy the process.
For you have need of endurance, so that after you have done the will of God, you may receive the promise. (Hebrews 10:36)
endurance: (1) The ability to do something difficult for a long time. (2) The ability to deal with pain or suffering that continues for a long time. (3) The quality of continuing for a long time. (definition from merriam-webster.com)
