If you have a goal which you want to reach, you also need to have in mind that everything in life requires a certain period, and so do the path which is necessary to pass to achieve the goal.
The real example is the mountains. The ascent to the peaks requires a lot of time and effort. There are natural parts of the trail and those challenging ones which are more interesting because thanks to them you can find out a lot about yourself, i.e., how persistent and steady you are to pass them and continue following your goal.
The trail is full of ups and downs just like the life itself. Just continue courageously, because the view from the top is worth each step you take.
