There are many things you can do to ensure that you are placing yourself for change. Learning to make simple nourishing meals, taking up a yoga class or joining a gym, joining a focus or self-awareness group where you can share your successes and your challenges.
Let us know your experiences when trying to change. The challenges and how you overcame them or what made you abandon your wishes. It's good to share and give you insight into what you need to do to change your life. I will reply to each one.
