Ask HN: What are the problems for non-programmers who need to learn to code?

Hi all, I am interested in the problems and annoyances you encounter in learning to program or applying that knowledge to your non-programming job.

For example if you are a trader who has to use spreadsheets, a data scientist writing python, a landscape gardener who built their own website, etc. Programming to me seems like it would be tough for those who don't do it full time with all the complexity us programmers throw in :-).
