We have our own set of goals and ambitions which we would like to see come true. But to reach there isn't that easy. It is more about the process than the result as the learning is more in the former than the latter. The process is a long arduous task where you tend to go through varied emotions altogether that you wouldn't know what to do at that moment. There would also be moments of frustration that you want to give up even when you are close to what you wanted to achieve. I am sure many of us have fortunately or unfortunately been in that phase where we get tendencies of giving up when we are so close to winning.
What is the reason? Is it because you are weary after working for too long? Is it because you can't stay away from your comfort zone for too long? Or is it that you don't want to do it anymore? If you have started the task, then you ought to finish it despite the obstacles and the struggle as it is certain to be a life lesson in the present or the future. Or else, does there has to be a strong reason for quitting.
The comfort zone is an obstacle but you never grow in your comfort zone as the more you stay in it, the far you will be from your ambitions and goals and you will eventually falter as there isn't any growth from your side. So if you want to grow, get out of your comfort zone, the process had to be difficult and unbearable, but in the end, it will all be worth it. There might be a hundred reasons to quit but always look for that one reason to stay and pursue what you are setting out to achieve.
Take every chance possible and don't wait for tomorrow or later because time is going very fast and a lot is happening in the world and the chances or opportunities don't stay for too long and if you don't hold it it is gone and it won't come back. Even if it comes back, it will not be like before, and maybe you might not be able to do it at that time. Timing also matters to an extent. All the things you want to do, don't push for later or some other time because there is no some other time, it is only Today, Now, Right Now, Right Here.
