My ideal self hm well its always a nice day when I dont think negatively which is an issue I have often. Not being rude to those around me which happens when you live with everyone day in & day out you rub on one another wrong sometimes. Having a productive day meaning I didnt sit in front of the tv all day or computer (does reading a book all day count as productive!?). Making sure my 3yo gets the most out of her day too.
Not sure if I understood your question though lol But those things are what I would consider me being my highest self as of right now in my life.
It will differ for each answer I am sure for me it would be to be able to give with no thought to oneself on every opportunity to do so. A selfless act so to say, routinely. Being able to help someone daily in a manner in which it cannot be repaid.
