An important part of meeting our commitments is to take them seriously. This is true whether the people we have committed to seem to take them seriously or not.
The attitudes that other people put into the projects they ask for help with should not influence how we treat the choice we have made. It can be frustrating when we have committed to help with something and the person we are helping does not seem to be putting effort into it. But we do not know what is going inside their heads. They may feel like they are working hard. There may be aspects of the project that we do not see or understand.
We have to take ownership of the part of the project that we have agreed to do, and if we are unable to do what we have agreed to accomplish, we have to be honest about that as well.
