Your life is the most important thing there is. What you do with your life is not so important. You have hopes and dreams for yourself, but trying to live up to those dreams takes you away from the most important thing there is, your life. There is no point in becoming something that you imagine you should be when you already are much more that you think you are.
You may have simple goals for yourself like trying to be nice, happy or mindful. You may have lofty goals like being president, curing cancer, or saving all sentient beings. You may just want to get through the day. You may do any or all of those things, or you may fail at any or all of those things. The most important thing is not that you succeeded or even that you tried, the most important thing is that you are alive. You are here. You are you.
