It is not what you leave TO them that makes them succesful. It is what you leave IN them that makes them successful. If you leave enough in them then you don't have to worry about what you leave to them.
However, if you leave enough TO them yet you leave nothing IN them then they'll ruin what took you years to build.
Even if you leave a billion-dollar company to them and you left nothing in them then they will ruin that company to ashes.
Build Character, Values, Lifestyle, and a Vision.
That's why the prophet was sent to teach us character. To build this character.
A person without character none can withstand them. Even if they had knowledge like an open book.
Islam is all about the lifestyle to live in this world. It's a guidance path on how to treat others.
Leave character, values, lifestyle and a vision. They may start low but they'll make it to success at the end.
It maybe baking or drawing or driving or writing or designing or cutting or massaging ...etc.
It's inbuilt in your system. You don't have to be a genius to be gifted!
Your gift maybe cleaning, start up a cleaning agency! It maybe baking, open up a baking college and expand! It maybe writing, start up a blog and share your words to help lives! It maybe massaging, start up your own massaging centre.
Discover that gift! You are not a pathetic loser! Life may have been hard on you but Allah doesn't leave His servants alone in hard times. He gave you Mind. How many verses end with, "Don't you use your intellect? Your reason? Your knowledge? Your understanding?"
Make that gift into use and start building your life!
