Offerings usually follow this formula. First you say who you are making an offering to, followed by a brief description of who or what your making an offering to, not only the common meanings but also what it means to you. At the end say what it is you are offering and light the incense, pour the nectar, or pass the cup, or whatever. You can say this simply or with poetry. You can say it in another language just as long as you translate.
Some people do very well right off others take longer.
It really does not matter. What is important is that you do your best. If they want perfection they are in the wrong place. Be aware that there are more advanced ways to do this. In the future you can learn them if you want to but this is a good place to start and adequate for our needs.
