We exist as `I' as `me', as `myself' but also as a part of `we' and a part of `us'. We exist as a person but also a person that others rely on because we fall into a particular category, such as partner, parent, friend, worker, counselor guide among others. Others expect the best from us as we tend to expect the best from them.
All that you can really do or the best that you can give to anyone or anything is your very best. No one, anywhere or any of your capacities can ask anymore of you. Because there is so much to you, it may not be possible to always give your very best in every capacity but the very least that you can do is try your best.
Wake up and demand your best from yourself for yourself and for others. Give the day your best. Give everything that you do today your very best, until you exhaust yourself or your very best.
