And yet, secretly (of course) we feel envy when the others do succeed and we face yet another false dawn of hope and disappointment.
Here's the bottom line: You can't help anyone else to prosper unless you can demonstrate prosperity in your own life.
There's no merit in wearing yourself out running after others until you run out of steam. That would be like giving someone a lift to a town 200 miles away without checking that you had enough fuel in your car. If you aren't whole and full and happy before you try and help another you will end up running on empty and, the odds are, they'll get cross with you for not being able to finish what you started!
