Challenges are good:
So this life is simple from some point of view, on the other hand it's harder from the other point. Well, no need to decide whether it's difficult or easy. The important thing is: 'Can you survive?' If you say yes! People will argue that even a pig survives, what's so great in it? You just need to ignore them. Pigs survive, they survive. You survive, then you survive. What's so bad in this? When people talk about the only motive of life they inspire us to live a life that is praised and worthy. A praised and worthy life ends with none other than 'death'. So how does that make sense to live in distress and working like machines throughout the life and end up in death? It doesn't. But even if it had, how is that differ? One day everything will be forgotten. Things fed up with time. We stop bothering about everything after a certain period.
In Human: Human is creative and can't be with the same thing or thought all the time. Change is the law of nature and human accepts it happily. Happy time, good time is all you want to remember on your death bed. So how to feed your creativity that everyone has? Do challenges. Yes! This is it. Do face challenges and survive, this is the best thing that will help you in getting satisfactory end. People don't get satisfied so easily. It's in nature, and there is no bad in it. You are not supposed to be satisfied at all until you're in last stage of life. To kick up your curiosity you can take your life to the level where challenges are most valuable things you'd ever want. Challenges help you in passing a good time with gift of your life. These keep you engaged with something and you don't bother about insane things and you happily enjoy your life, your challenges and your survival.
Persistence: look, nothing is persistent in world other than change. What makes you feel alive is that you are accomplishing something that you are getting a victory that you think of something to do and you could make it. Challenges give you that chance, challenges give you platform to make a difference. Challenges give you the reason to survive. Challenges get you time sometimes good sometimes bad, you face this time, you enjoy it too, and this is what life is about. The little toughness in tasks makes you feel alive and this is called challenge. So challenges are good.
When you are born you had no reason to live, but you had no reason for not living too. When you'll observe these people around you, you'll come to know that people also don't have any special thing to do in life. They just find their own reasons, little inspirations to survive. This is how life works. But you can choose your own reasons. You have a free will to choose your motive and job to do for your lifetime. But the thing is if you choose a task that is challenging, it will make you feel alive. So live alive.
