As a young man, i have had some experiences and this is totally sponsored by the experiences of life.
You may have had your share of this fact. Or chances are that, you will soon.
There is a school of taught that believes that, "EXPERIENCE IS THE BEST TEACHER".
WAIT!
Whose experiences here?
You can learn from people's experiences.
You can learn from your own experiences.
In achieving a great feat, you need people. You can't do it alone.
*KINDS OF PEOPLE*
CATEGORY 1
Those who were sent to assist you while finding their own success in it. They are working with you in vain. Somewhere, in their being with you, they try to pull some stunts at achieving theirs. They will not leave, as long as they keep benefitting.
CATEGORY 2
Those who will come at the initial, and it'll look like they're staying. Their departure would hurt the most, do not build the success of the feat around them. They may swear never to leave you. But, like Peter, when they are gone, it will take so much at worst, the Grace of God not to get frustrated. Chances are that, these ones, you have made them part of your life. They leave when they feel a decline or lost of hope in anticipated benefits.
CATEGORY 3
Those who will come at the initial and leave never to return. Know when their part in ur success story is over. These never knew what they wanted. They just wanted to be secure at the time. They may/may not be excellent. However, their absence may not be felt as much as their presence.
*CATEGORY 4
Those who will keep coming and going. They are as unstable as water just like Reuben. Though they have nice attributes of self, but they can not excel because of their instability. They are double minded. So is what they put their hands to do.
Never build your success around these ones.
CATEGORY 5
Those who were never with you, but your fame 
CATEGORY 6
But there are the ones that stay through, and don't mind personal benefits, whether they get it or not. They are born selfless, "Destiny helpers" if u may. It don't matter if there's a stake for them.
As the sole driver of your vision, one important key to note:- KEEP FOCUS STRAIGHT
Thanks
