To a company, you are just an employee.
The day you resign, your work cubicle will be replaced. Your absence will be missed for a day, then the company forgets you. They went on to make their money for they need to, and they have no time to grieve because the expectations they have to fulfill.
This is why, DO NOT MIX WORK with FAMILY. Do not take your work home, cast your family aside and forget about giving time to your children. Because in their hearts, you are never replaced. Because when you are gone, everyday you will be missed. If anything happen to you, it will be your family and close friends crying like crazy for you. Because to them (even though you are one person) you are their world.
So reset your priorities. Be a good worker.. but be a better father/friend/son.
