Being a caregiver is by no means easy. It will not give you awards, it will not make you rich, and for the most part can be thankless depending on the client or individual you are taking care of. However, on the other end of the spectrum, it can be personally rewarding with the knowledge that you are helping someone who cannot help themselves. Sometimes the individual can be mean and thankless while other can be truly sincere in their thanks and pay you compliments. But doing this for the sheer reasoning of being thanked should not be the reason you do it. Being a caregiver means more than receiving applause, being thanked, and getting a pat on the back. If you are doing it for these reasons, guess what? You are in the wrong profession.
You do it because you have a want, desire or need to help people. Some people feel they do not have a choice in the matter due to it being a family member and these people are more prone to caregiver burnout.
