Develop a long-term view. Remember that we all stand somewhere between the first three chapters of Genesis and the last three chapters of Revelation. God has been working on his plan of redemption for thousands of years, and you will not accomplish the redemption of the world alone in one lifetime. Remember that everything takes much time. Learning a language and culture are long term projects never really completed.
Relationships are important and take time.
The hassles of daily living in many cultures take time. Paper work is necessary and takes time. Contact with supporters takes time. Learn interdependence, not independence. Rather than trying to do things yourself, realize that you really do depend on other people, and they depend on you.
