Life has to go on friend, despite the difficulties and how exhausted you may be. It is you who can only inspire and push yourself. If I am not willing to inspire my soul than no matter how many inspirational books I read or get the best answers from the world, nothing would be helpful.
We humans, have been blessed with everything by God and you are the best judge for yourself than anyone else. Know your positive and best strengths and work on them. The bad time is to teach you a lesson that keep on fighting at every step and you are required to be successful. A small huddle should not be a great reason to stop your strength and willpower.
Do what you like the best and love what you do. Exhaustion will never last long. Have the ability to conquer yourself and then only you can conquer the world.
