Going to church and praying for changes in ones life is the seeking after luck although Christians do not use the term.
Throwing money in fountains is also judged to be lucky. This goes way back in English history to pre Roman times.
It is true that some people are luckier than others. This is because their lives offer more opportunity for apparently chance occurrences.
Someone who sits at home will have very little luck (either good or bad) in their life. The song 'Eleanor Rigby' by the Beatles sums up such a life very well. It is better to die than to live such a life.
The unlucky may blame the dullness of their life on poor luck. Life presents them with nothing because they do not present themselves to life.
Interesting people and adventure surround such a person and yet they will never meet because the unlucky individual has sealed himself in a grey bubble of monotony.
Interesting people do interesting things in their lives. This is why the dullard can only meet other dullards- people of imagination simply have other things to do.
The bad news is that your life will remain empty for as long as you let it. The good news is that it is possible to change.
Your luck can change. This does not involve positive thinking, magic candles or voodoo. Simply meeting new people will change your luck for the better. This not wishful thinking.
