You don't say how old you are, or exactly what you want to know.
While in general older people take longer to learn, individuals have a way of confounding the generalisations. And for everyone, it takes as long as it takes. As for work, it takes a lot of persistence and luck, however young or old you are.
Now, I'm not sure what else you want to know, but may I suggest you do a search on here anyway, becasue as you say, most of these things have been asked - and answered - before.
