I read a book once by someone called Wiseman (which I thought was apt
) and he said that luck is a frame of mind. If you talk to people and go to places you are more likely to have a circle of friends and acquaintances. That means that you are more likely to find out about things like jobs that are going, or bargains to be had, so are more likely to get them. If you stay indoors and refuse invitations to parties or events then that won't happen. You aren't unlucky, you just weren't there.
Similarly, if you always buy raffle tickets then of course you will win things, and probably forget the times you didn't. If you only buy them once a year, you probably won't win, but will almost certainly remember that you didn't. Again, it's less about luck than numbers.
There is an often quoted saying that 'the harder I work the luckier I get', which applies when people are told they are lucky to have a good job, or a decent salary.
Some things, like illness and accidents happen for no reason, and can be put down to bad luck, but without wanting to minimise the trauma of that, if you see yourself as being lucky to survive, or to have been old when you got ill, it can help with general happiness.
There is an undeniable 'Pollyanna' element to his outlook, but on the whole it seems sensible to me.
