I learn from most of my mistakes. Unfortunately not all, because I'm thick.
You don't need intelligence. You just need to remember what happened the last time you did whatever it was when it didn't work, and try doing something else the next time you do it!
We need mistakes We can't go back in time to correct them, but what we can do is try to avoid repeating them.
An odd quote came to mind. "80% of people are caused by accidents" or something like that?
What it means is we as people will naturally make mistakes, as it is how we find out the things that work.
When I started on the railway a railwayman told me "It is ok to make mistakes. Just try not to make any big ones!"
But seriously, if we don't learn both by our mistakes and themistakes of others, how will we be able to live?
The foolish person in life is the one who says they never make mistakes, as what they are saying is that they lie to themselves!
Yes, some of us make more mistakes than others, BUT the ones on the path to success are the ones who tried many failed paths before and learned which were the paths to success!
The least successful education teaches us the ways to success without teaching us about the failures. If we do not learn about the failures, then how can we adapt to new situations we have not come across in the future?
Think how many things that failed before ways were found to succeed?
Human flight! Now that had many failures before people invented clever ways to make it happen!
