Do not let difficult people who always want more taken advantage of no matter what. You have to stand up for yourself and let others know that you are doing all that you can. Tell them to stop wanting more and maybe you should start to ask for more out of them. Do not worry about hurting someone’s feelings. You are entitled to let others know that you are important so that you are not being taken advantage of. There are people that are close to you that may ask too much from you and you have to set boundaries. This is going to give you more respect for yourself and give you the ambition to move on to something that you want to do. You will feel better about it when you are done and maybe the people in your life that always want more will back off and start to appreciate what you do for them.
