A website is explaining the benefits of owning your own business. It says:
You get to pick and choose when you work.
When you "get to" do something, it means that you are allowed or able to do it. So this is usually something that you want to do.
Technically, "pick" and "choose" mean basically the same thing, so it's odd that you would use these two words together, but they are often used as a pair anyway. Using this expression gives the sense of having more freedom of options than just using "pick" or "choose", which can give the sense of just choosing from a set list of options.
