Grammar: -ing verbs

This might be rather advanced grammar. Let's look at these sentences:

Being rather shy, he preferred not to join in the conversation.

I don't have much free time, working full-time.

Not wanting to cause trouble, I remained silent.

Here, the -ing verb means 'because ___'

So, here is the meaning of those sentences:

Because he was rather shy, he preferred not to join in the conversation.

I don't have much free time, because I work full-time.

Because I didn't want to cause trouble, I remained silent.

Sometimes the -ing phrase will include other words such as: 'like this', 'as I do', 'as I did', etc. The meaning is still the same.

I don't have much free time, working full-time as I do.

He should be ashamed, wasting time like that.

Wanting to help as she did, she waited for an opportunity.

The important thing to remember is that the subject will be the same in both parts of the sentence. For example, 'Waiting for her boyfriend, he was really late', doesn't make sense. We see that a woman is waiting, so you must continue the sentence talking about the woman. 'Waiting for her boyfriend, she was getting angry,' is okay.

As you know, -ing verbs can be used in many different ways, with different meanings. This is just one use.

Can you make a sentence using this grammar? For example, think of something that is difficult for you. For me, being lazy, I have trouble getting up in the morning. How about you?
