The truth is nobody owes you, so stop living a lie, stop feeling entitled; your uncle, your brother, your old friends, they can help if they want to but it is not your right to get help from them, so if they don't, you can't hold it against them. You would have to help yourself
You can't live your life building other's dreams at the expense of your own.
There is this big picture in my head of where I want to be and you know what? I have come to understand that it only takes my commitment and God's grace to get there.
