Generally death limits it...
Depends on what you want to do.
We are always stronger than we might feel or think.<br />
We are never given more than we can bare.<br />
When we feel we just can't anymore it's time to seek help ither of a friend or a professional.<br />
Ither way I hope you have a better day today.
In what regard? Distance, work, relationships, being bored. Make a decision and give some clue which direction you refer to. As right now, as it is, it means nothing and only answer you get will be people trying to assume what you mean. In other words, meaningless.
No. The only limits are those you accept.
