In today's age young adults are so easily distracted, its is important to have focus, have focus on your goals through directing your attention and efforts to your desired location; your goal. With the influence of your social life and friends can make it hard at time to focus on your studies or assignment thats due. I would say that it takes a large amount of maturity to focus on the task at hand.
The average person is said to not be able to focus as much and if they are able to, they are unable to maintain it. It usually takes average talent, average time to do extraordinary things, it is what will determine whether you will achieve greatness. I would say that one reason average people dont learn to focus is that they live under false assumption that it requires great amounts of effort and will be a strain on them in some way. It is important that with maturity that wise decisions are made and the first thing to do is to focus on achieving your goals and from there make wise decisions.
This is a valuable life lesson of nature which i myself is still learning.
