You don’t think about it too often, but there is a last time for everything. Last time you brush snow off of your car in a snowstorm, last time you climb those really long flight of stairs you hate. Last time you cry, last time you have to wait in line. Last time you have to say goodbye to someone you love, last time you have a cold.
If you just think of it a bit more, just have it with you throughout your days, you’ll realize you might one day miss all of the things you find hard. You’ll realize you might be able to endure it.
You might even enjoy it. It’s a part of the time you are given here. Treat it that way.
