<Rather than worry about future verb-tense conjugations, many languages have a handy feature of sticking to infinitive verb forms after modal verbs. In less complex language, this means that if you use words like “want,” “need,” “would like,” “should,” “may,” “can (able to)” in their standard present-tense conjugation with, say, “I” (“I want,” “I can”), you can follow them up with the dictionary (infinitive) form of the important verb you wish to use, such as “to travel.” When you think of it, the essential difference between “I want to travel” and “I will travel,” while important, is not significant when you want to convey a simple meaning.
<To keep it simple, I’d recommend you learn just “I want,” “you want,” “I can,” and “you can” to begin with, especially if your exchanges are directly with one person (since the he/she/it/they pronouns will be less relevant in that situation). The word “want” can be an okay replacement for the future tense (“want to speak” instead of “will speak”). “Can” is good to use in many direct questions, so rather than “Do you speak Italian?” I would go for “Can you speak Italian?” The point of doing this is to use the standard dictionary form of the word “speak” (parlare in Italian) without needing to conjugate (change) it. “Need” (or “have to”) is good for any kind of obligation. So rather than “I start work at nine,” I might say, “I need to start work at nine.” The meaning isn’t precisely the same but it’s close enough.
Good tip from "Fluent in 3 Months" by Benny Lewis (don't take that title seriously though).
