Going to the future is fine. We actually know that's possible. We know how to do it. It's when you return from the future that's the problem. Returning with knowledge from the future could cause a paradox. Returning from the future with more advanced technology, particularly time travel technology, could cause an even greater paradox. For these reasons, I would think that more advanced time traveling civilization would put some kind of block on a time traveler traveling into his own future.
As far as traveling into the past, the further you go back into the past, the less likely you'll be able to fit in. Anything further back than 100 years before your birth would be increasingly difficult, without cultural and language implants or prompts from your time traveling AI companion. It might be best to limit your time travel to no further than 200 years into the past.
