You may be flying a private jet because you can afford it and probably because it's a necessity. Well, others may walk on foot to get to their destiny, and that is because that is what they have and can afford.
We all have to acknowledge that life dispenses opportunities with unequal value, and we must respect each other for that.
We all use what we have and can afford, and the minute we realize that as long as we can get things done based on our own abilities and capacities, then nothing matters. We should just be contented that we can get things done in own different ways.
