Kipling had something to say about this.
From "Certain Maxims of Hafiz'.
If he play, being young and unskilful
For Shekels of silver and gold
Take his money, my son, praising Allah.
For the kid was ordained to be sold.
And as said rather more pithily above, if it flies, floats or f***s it's always cheaper to rent.
And "If you want to make a small fortune, start with a big one in aviation".
Read, mark, learn...and inwardly digest...
