Getting a title (e.g. NM, or even FM) is possible for any normal person who loves chess and is ready to spend a few years studying it & playing in tournaments.
Not so sure about GM level. I am an optimist who believes that sky is the limit, but many GM-friends of mine think that only very gifted players may reach that level of expertise.
In the past year or so I've added a few items to my bucket list, some of them serious, others not. For instance, I've made it my personal goal to convince my AP Government teacher to make it a class project next year to get me elected mayor. I DO want my name on the ballot, but it would be silly to expect anything else.
But on a more serious note, I decided to pursue gaining a title in chess within the next few years and I was curious about learning some roads that have been taken by people that have reached that point. Some are prodigies and others through hard work. Details would be appreciated
