While we idealise rich people - they have their own struggle - they might have made their own mistakes
But we only see where they are today. I read most of the times that many rich people failed while trying to establish their business - I am a complete failure - never have ever lucked sided me in my life time
The important thing is not to measure other people's success as a benchmark for your success and compare other people's efforts to what we are doing either from failure or success, because basically everyone has a different response to situations of psychological stress that is influenced by mindset and experience.
Complaining is a natural thing but it's not good if you keep sinking in that position, in fact it will make you farther from your goal because complaining will never solve the problem and if you keep silent and do nothing after your failure, you are guaranteed to fail when you are no longer doing anything for your goals.
