Well, time does change, and so are our priorities in life as you said. We might be gamers and love playing games, and when someone loves games, they also love watching others play on streams and videos and stuff, we do that all the time until we get married and have a family to take care of, that is when a full stop is added to your activities that you used to have before because you don't get enough time for yourself and your activities that you once loved.
That's how life is, it gets difficult at times but it also gives you pleasures sometimes, it's a total rollercoaster that never stops and you keep going up and down and sideways sometimes, even if you want it to stop sometimes, but the control is not really in your hand so you have no option to stop it.
It is important that people learn to adjust their behaviors to their new circumstances in which they are in, gambling can be without a doubt an incredibly exciting activity, however the same can be said about raising your kids as everything they do has the potential to become a memory you will never forget, so if at some point you find yourself in a situation in which you cannot gamble anymore you must not despair, and instead accept those new challenges as they may offer you a completely different sense of excitement.
I think that the most time the life makes you change your habits. But the same time you get another ones. So you don`t lose your hobbies but only replace them. And when you become an old one - you have some fun to remember. But i can`t say that it is interesting thing to remember how you watched someone`s gambling.
