the ultimate goal

An "ultimate" goal is the greatest or most difficult thing that you want to achieve. You can think of goals as falling into different time periods:

• An immediate goal is something that you're trying to do right now.
• Your ultimate goal is the thing that you want to do in the end. This can be the end of your life, or in the end of some other period. For example, an ice skater might say that her ultimate goal is to win a gold medal in the Olympics, although she might do that when she's only 18 years old.
• A short-term goal is something to be done in a few weeks or months.
• A long-term goal is something you want to do in months or years.

In the example above, the "ultimate goal" refers to the goal that you want to achieve at the end of the project.

(my/our/the) goal is to (do something)

When you're expressing your goals, say "My goal is to ___":

Our original goal was to raise $5,000, but we've already done twice that.

have (something)(adjective) by (a day or time)

This expression is used to talk about something that you want to be a certain way by a certain deadline. You can't use just any adjective in this phrase; there are only a few adjectives that will fit. These include:

We need to have this finished by Monday.

You'd better have it done by the end of the day.

I don't know if it's possible to have it built by then, but we can at least have it planned out and designed.

(something) is available to the public

"The public" means "most people". If a store is "open to the public", it means that anyone can come into the store. If a store isn't open to the public, it's either closed or restricted to private use.

If something is "available", it means that you can get it or use it. So "available to the public" means that anyone is able to buy it. Use this to talk about products that are being sold to a large number of people.
