“All right, we'll pick it back up in the morning.”
You've been working hard on a project at work all afternoon, and one of your team members suggests that you should call it a day. You agree, and you want to tell everyone that you should all continue working on it again in the morning.
All right, we'll pick it back up in the morning.
"All right" is similar in meaning to "OK". It can be used at the beginning of your sentence to agree with what someone said.
All right, that sounds good.
You also say this when you've made a decision and are ready to announce it to people:
All right, how about this: I'll pick Oliver up after school and take him to practice, and you can go with Emily to the dentist.
Use "we will" to express a plan that you just decided on. When you're talking about a plan that you already had, say "we're going to ___".
This phrase means to continue doing something that you had stopped doing. This is useful for talking about work, lessons, games, or other things that continue for more than one day:
One thing I like about listening to audio books is that you can pause them and pick them back up later without searching for where you stopped.
I didn't speak English for a few years, but I was able to pick it back up with no problem.
Another related phrase is "pick up where (one) left off". This means to continue something from the same point that you stopped at last time:
OK, well it looks like time's up, but we'll pick back up where we left off tomorrow.
