If your work seems too difficult or tedious, make it more meaningful. Connect what you do with who you are, and it won't seem like work at all.
There's a reason why you're doing the work you do. Remind yourself of that reason, and of the benefits your work creates for yourself and for others.
Deep down inside, you long to make a difference. The work you do, the efforts you undertake, give you the opportunity to fulfill that longing.
If there were no benefit to what you're doing, you wouldn't be doing it. Remind yourself of why, refresh your sense of purpose, and you'll make yourself thankful for the opportunity to do whatever you must do.
Imagine how awful it would be if you had no way to matter, no way to make a difference, and no way to positively influence life. The work you do, whether it is your formal job or your chores or any other useful effort, enables you to have the influence you seek.
