Think about the time and mental energy that you spend fretting about things that you cannot change. We stress about the weather. We worry about whether others will fulfill their commitment. Whether people will like our idea or if people will like us.
How much better off would we be if we accepted more things as they were? Even if it is just for today, try to be at peace with "what is" and who you are. The clear thinking that comes from serenity will help you craft a better tomorrow.
