The fear of the inability to achieve EVERYTHING has stopped so many people from doing ANYTHING thereby leaving them with NOTHING.
Yes, with what you have right now, you might be unable to achieve everything, but the moment you realize that in everyTHING there is THING, then it will dawn on you that everything is simply the combination of different things.
I also do agree with you that the thing you can achieve presently with all you have might be THIN but as thin as a broomstick is, when combined with other thin sticks and tied together it becomes a BROOM.
So rather than sit and do NOTHING, why not arise and do a THING with all you have now and add it to another thing that comes your way thereafter to make it SOMETHING and with extra additions along the line, you just might see yourself achieving EVERYTHING in no time. But first it all starts with a THING.
Remember we need a BROOM to clean the ROOM but we need combination of THIN sticks to make a broom. Get to work no matter how little the resources you have.
Why do nothing when you can achieve something with the little things you have at hand?
