Break your hard work into component parts.
Every kind of work or challenge in life has difficult parts or things that might not be so easy to do. It is necessary to keep our mind to understand and handle the situation with a big picture of the whole thing. If we do not see the big picture, then we might not understand the problem statement but difficult you shouldn't do it; and if you can change it or manage to fix it to be less difficult, it stops being so "hard" and instead is just "done". Break your hard work into component parts; it makes it easier to see where the obstacles are so you can be prepared to overcome them.
