If you believe that luck exists, you can probably find yourself unlucky at times... Not everything we do works out, particularly I believe that everything happens when it needs to happen, I don't believe in luck or bad luck.
If you are prepared to take advantage of the opportunity that is foreseen, luck has certainly smiled on you, but if you are not prepared to take advantage of the moment then you are unlucky, and you have lost the chance to live that moment.
Luck exists to chase your goals, if you stick to the point you will understand that luck is useless, for example, If Messi player kicks the ball into the goal he may be lucky to see the ball enter and score a goal , as well as if he doesn't kick he won't have that chance.
Another example: If you buy a Coin and tomorrow you see it go up 100%, part of it can be considered lucky because you hit the target, that is, part of the luck will depend on you and the other part of chance may happen, maybe not.
So... luck only exists for those who seek, sometimes it also happens for those who do not seek, and this is normal.
