We do a lot of things in a day and everyday we get a lot of challenges in our life. Sometimes, we feel so weak in front of those tasks/challenges, in that situation someone tries to find a way to quit the challenge. But it's not a right thing, which we supposed to do. We have to motivate ourselves through some Great movies/Books/Mantras or by Meditation. In order to achieve something or to complete any task properly, we really need a Great focus and it is only possible when we keep ourselves inspire. We should think that nothing is impossible here in this world, if a small ant can survive on it's own, and why don't we? We are more powerful, more conscious and we have everything more than any other species. Whenever we feel weak, we should think of weaker species, and more worser situation than ours, it could help us to complete any task.
Hope this helps!
