(This is to my friend in New York who is rebuilding himself)
Life is beset with ironies. It is difficult to know what is good fortune and what is bad. Remember that any fool can make the most of his victory, it is truly the genius who makes the most of his loss. To glean from it what he can and turn it to his favour. Learn to be objective in triumph and loss, endeavour to treat both equally. What does this mean? It means to neither be too high nor too low. Contentment lies somewhere here.
Try not to be haunted by the past, for it is gone and even God cannot change it. As for the future it isn't yours, so don't fret about things that are not, and may never be. Do the best you can, where you are, with what you have. Nothing more can be asked. Beware the critic, their words are wind.
Be your own judge. You will find yourself judging others, this is natural, but it doesn't necessarily mean you must voice it aloud or behind their backs,
The universal currency is time. You can lose money and make it back, lose time and it's gone and worse still you've no idea how much of it you truly have. Therefore you must make the most it everyday. Early to bed, early to rise makes a man healthy, wealthy and wise. Have the discipline to do this and the discipline to use your time well and for the right reasons. (the right reasons are only truly known by yourself) Discipline is painful but so is regret. Everyone whether poor, rich, young or old will suffer a measure of both these pains. It is inevitable. However, the pain of discipline weighs ounces and diminishes over time. The pain of regret weighs in tonnes and increases over time.
Ultimately the ground we tread on is uneven. Remain sangfroid, do not allow your equilibrium to be unbalanced for too long, but recognise and admit your emotions this is necessarily to know thyself. The first step starts from within. Life is 10% what happens and 90% how you deal with it.
