Perseverance
Definition:
Steady persistence in a course of action, a purpose, a state, etc., especially in spite of difficulties, obstacles, or discouragement.
It's difficult many times to stay a predetermined course when things become difficult. But you must also understand and realize that the higher up you ascend in life and in your purpose, the more difficulty level only increases. The good news in this is that the lessons you encountered prior to the current ones you presently face are designed to assist you with finding the answers you need for where you are.
One thing you must be mindful of is not allowing discouragement to settle in due to the obstacles life throws at you. When you have an attitude of perseverance, it comes mostly from having faced many challenging and daunting conditions before. This also comes about from realizing that you were made to be a winner, no matter what the case.
You again must find your proverbial "center" and buckle yourself down with the mentality that you will stay the course of your destiny, come what may. Life will always pose its challenges, each with its own entailments, nuances, and constant, continual moving parts. You cannot deviate from your purposed course that has been set before you. You have to maintain the consecution (chain of reasoning) in the direction you are headed, knowing that you will always face tribulations. There are always things that will come against you but have you a made up mind to press past the obstacles that betide you?
Determine in your heart and mind to be persistent with the successful course of action you have decided to take. The success of you fulfilling your purpose depends on this. Know that life's storms will come, but they're only temporary. You're the permanent factor in the equation. Do not allow life to cause you to quit because of impermanent troubles.
