As a parent (s) with a child (ren), it's your duty to leave something special for them, if it's a business, get one so your children can inherit. This is because they can't inherit your job, but they can continue your business where you stop. You know a successful business takes years to achieve, it doesn't matter what stage you are at now, start something that is inheritable.
If you don't have any business, you can sit back and think of a business idea from time to time when you are free.
Time is your greatest enemy.
