Hi Julia, I personally like to start out with 10 of the most common 50 verbs of a language, so that you can already say a lot. My suggestions are:

1. sein - to be

2. haben - to have

3. machen - to do

4. werden - to become

5. gehen - to go

6. wollen - to want

7. sprechen - to speak

8. sehen - to see

9. wissen - to know

10. kommen - to come

Then, of course you have some German verbs like können (can), sollen (should) and müssen (must), which don't really function as real verbs in English in terms of conjugation, but in German, they do.

sure, some of them are mentioned here, besides you can use this webpage to learn faster

Try to get these negations and their meanings right from the very start:

Ich muss nicht = I do not have to / need to

Ich darf nicht = I must not

This gets messed up a lot I feel ;)

I highly recommend these from Memrise. You can even learn how the verbs are conjugated (present and perfekt). :)
