Life is a process. It is a learning process. Learning to let go of outcomes and to observe rather than to control. Control of anything is impossible. It's impossible to control what my kids do. They will be who they are and all I can do is to observe and support. Control of any other person is simply not possible. Trying to control my own thoughts, feelings, emotions, is also impossible. I know that I am doing the best I can with what is available to me - my energy, the skills that I have learned from my life experience. I do not need to try to do more than that.
If I need time alone, I need time alone.
If I need sleep, I need sleep.
Sometimes I can easily meet those needs, sometimes not. But I can't control those needs. I can support myself in terms of the food I eat, the rest I take. Whole hearted self acceptance is key.
