Check out this thread and Tommy Hodgins 's awesome answer, which also holds in a more general sense.

For me, I wish I had known how important it is, to carefully plan ahead and be responsible for the code. Would have saved me so many code rewrites!

I wish I'd known that I would have to maintain the code five years down the line...

Everyone in the industry had some great ideas related to coding, in my point of view there are lots of things which need to be correct on emergency basis, we at Unique Cosmetic Clinic provides best botox injections services which is famous in all over Canada.

Coding.

I had so many good ideas. Unfortunately I didn't write them down, but I wanted to create all of them. Except I didn't know how to create user interfaces, how to write good algorithms, and I generally didn't know enough BASIC to do them (let alone knowing BASIC is not the best choice for them).

Yeah, some formal training would have been nice before I got my C64.
