Title: What's the difference between "I look forward to" and "I'm looking forward to"?
Question: I just don't get the reasoning behind which one is correct in which situation.  Typically I use the wrong one, or I use them when I'm not supposed to.

Answers:
sents: text: If you mean both in the sense of anticipating something, both are equally valid.
text: However 'I look forward' is more formal; it's the kind of thing you would write in an official letter.
text: A typical example is the closing statement of a cover letter for a job application:
text: I look forward to hearing from you soon.
text: 'I am looking forward' is less formal.
text: You would rarely say to a friend on the phone 'I look forward to visiting you next week.'
text: You would say: I'm looking forward to visiting you next week.
text: I'm not sure why others here have suggested this is wrong.
text: You wouldn't say 'I run towards the train station!'
text: , you'd say 'I am running towards the train station!'

sents: text: Hmm, okay, a totally non-grammatical (probably, and thus very likely totally wrong) answer by an avowed non-grammarian (who nevertheless described and describes himself as a grammar-nazi at times):
text: "I'm looking forward to" means I'm doing it right now, this very instance, like in Elendil's example of being on the phone with a friend
text: ; I disagree that it's about formal vs non-formal
text: , it's due to being on the phone with that friend in that moment, so of course you'd be looking forward to meeting said friend at that very moment .
text: "I look forward" means looking forward in a general sense; like, you'd not think about meeting your friend every second of the day, but the anticipation would be in the back of your mind all the time.
text: That's my take, and I'm sticking to it. ;-)

sents: text: Look forward to is a phrasal verb that means to await eagerly .

text: He looks forward to graduating this year.
text: We dare not cancel the trip to Banff.
text: The kids have been looking forward to this for ages!
text: Both were looking forward to spending a wonderful evening together, but the weather cruelly disrupted their plans.

text: actually looking forward to vacationing with us for three weeks.
text: This house is super boring!
text: Even though he knew it would be difficult and unpleasant, he still looked forward to having a heart-to-heart conversation with her.
text: The sentence
text: I'm looking forward cannot be interpreted to mean eagerly awaiting , as it would have to be followed by to_ .
text: Thus, it can only mean one thing: I am directing my gaze (or view)
text: forward where forward is an adverb.
text: This usage, however, is not common in regular conversation, except in very few circumstances.
text: Nevertheless, it is definitely acceptable to say: I'm looking forward to it! to indicate that one is eagerly awaiting an event.

sents: text: Assuming you mean "I look forward to ..." and "I'm looking forward to ..."
text: , they are essentially the same thing.
text: However, there is a slight difference.
text: the -ing on "looking" is a present participle.
text: So if we consider "look forward to" to mean "anxiously await", then we can rewrite the phrase as: "I anxiously await your visit", vs "I am Anxiously awaiting your visit".
text: So in this case, "look" and "await" are the verb, and "forward" and "anxiously" are the adverbs.
text: So it's sort of a active/passive thing.
text: "I am" versus "I".
text: You would not say "I looking forward to" or "I am look forward to".
text: It is effectively the same thing as "I look" vs "I am looking".
text: for example "I look good" and "I am looking good".

sents: text: My take: 'I look forward to hearing from you' means you expect something to happen. '
text: I am looking forward to hearing from you' means you are now excited about a future event.
text: Both cases can be used when you expect a reply from a person you email.
text: Still, the connotation is different.
text: Another example: '
text: I see an accident happening'
text: means you expect an accident to happen. '
text: I am seeing an accident happening' means you now see an accident happening.
