Don't want to be an average lazybum

I have asked myself, if I am faced with the prospect of living with marginally decreased cognitive function but living long and dying young with full mental capacity, which route will I most likely choose, I am compelled to pick the latter due to how precious I see in intelligence. The ineptness to hold onto something, no matter how hard I bury it into my mind, is a scary thought. I also have certain things I want to remember as well as talents that reside in my head that I don't want to lose. I see the ability to answer questions, as well as form questions, as one of the greatest gifts a person can have. I don't care how beautiful a person is or how much money a person has or even the royalty lineage of a person or anything about them. I don't care who they are until I know how deeply how they think. I care the way how they think and rationalize things through their thought process. That is beautiful. 
Now I am faced with the prospect of becoming something I cannot stand. I am looking at the chance of my efforts that I put in to achieve what I want to do, are going from the sublime to the ridiculous, hence being too average - too much to procrastinate myself as if time given to me is nothing but free. I have only got the last thing I need to do for myself, but it's taking forever. So near, yet so agonizingly far.
To be that person who is content with just pulling the groove of nine to five job, it's not an ideal person I want to be. And with the inflation ever rising, and the figure can only be climbing still and not to mention your financial burden and all that increasingly weighted on your shoulder, you just don't want yourself to even have that idea of taking up a second job just to make ends meet. Irrespective of being distinguished or small fry or even playing second fiddle to someone. 
I may not want to be that person who changes the world and shift the way how we think, but certainly I would want to be that person who break new ground in the area of my interest or do something meaningful in life, that one day when I look back, I would feel accomplished. This way, I am not just doing something which I am fond of, but when it matters most, I am doing something meaningful and that I have passion in everyday!
No one who was average and being a lazybum ever done anything meaningful in life. I have a chance right now to do that and I want to hold onto that chance. Looking back on history, everyone who did something great was smart and had passion to a certain extent. Good or bad, they were all brilliant people. I don't want to be a vegetable, being one is worse than death. And I think it s time for me to roll up my sleeve as procrastination is the thief of time!
