Another way is to watch the big players who are playing regularly and take them as our role models and practise the game aiming to get to the position of your role model. Many people were inspired by the name Tendulakar got and they started playing cricket.
Another aspect is the guidance that we get from our family members and teachers. If any of our family members is good at a particular sport or game, we will also get interested in that game.

Even this challenging situation would ease
I think for any sports, watching matches would help understand the games better and we get to know more players and their countries as well. So watch matches of your favourite team or player in each sport, you will develop an interest in sports.
