There's still a lot of nature vs. nurture to that. A lot more experience = a lot more failures.
Very few worthwhile projects are ever successful on the first attempt. Failure is just another useful metric giving guidance on the re-formulation of the problem and the solution. Failure has nothing what-so-ever to do with guilt.
For the longest time as a young man I did not understand this. I though something was wrong with me because I failed so often.
